Humans may have first visited Yosemite as long as 8,000 years ago, and there is evidence that people have lived in the area for nearly 4,000 years. In 1849 the lives of the native Miwok population changed dramatically as the California Gold Rush brought thousands of miners into the region, resulting in a massive disruption to the way of life practiced by the existing people. By the 1930s the population of Native Americans had dwindled to the point that the last Indian village was disbanded, and by 1969 the last private Indian residences (by then solely inhabited by park employees and their families) were abandoned.

The beauty of Yosemite Valley inspired early visitors to the area and led to concern about exploitation by commercial interests. After prominent individuals advocated for its protection, on June 30, 1864 President Abraham Lincoln signed a bill granting Yosemite Valley and the Mariposa Grove of Giant Sequoias to the State of California as an inalienable public trust. This was the first time in history that the US federal government had set aside scenic lands for the purpose of preservation and public use. Following further lobbying by the conservationist John Muir, additional restrictions were put in place against grazing in the subalpine meadows surrounding Yosemite Valley, and on October 1, 1890 the area was declared America's third national park. However, as Mackinac River National Park in Michigan became a state park, Yosemite is the second oldest that still holds the "national park" title today.

Despite its national park status, California controlled the initial grant area until 1906. Following the 1906 San Francisco earthquake that city began looking to Yosemite's Hetch Hetchy Valley as a source of drinking water and hydroelectric power, and a bitter political struggle ensued between environmentalists and the city. In 1913, with the passage by Congress of the Raker Act, permission was granted to San Francisco to build the O'Shaughnessy Dam, allowing the Tuolumne River to flood the valley. Today, efforts to remove the dam and restore the Hetch Hetchy Valley continue.

Yosemite is best known for its impressive granite cliffs and domes. These formations were born approximately ten million years ago when the Sierra fault began uplifting the Sierra Nevada mountains, forming relatively gentle western slopes and more extreme eastern slopes. Erosion, combined with at least four glacial periods, exposed the underlying granite and resulted in many of the cracked, rounded, and weathered formations that make the park famous. Streams cut deep, narrow valleys, while glaciers covered the area in up to 4,000 ft (1,200 m) of ice and generated wide, U-shaped valleys.

The Tuolumne and Merced rivers are the two major river systems in the park, carving canyons that are 3,000 ft (910 m) to 4,000 ft (1,200 m) deep. In addition, smaller rivers flow through the extreme elevations, generating some of the most impressive waterfalls in the world. In Yosemite Valley, Yosemite Falls, at 2,425 ft (739 m), is the tallest waterfall in North America, while Ribbon Falls has the highest uninterrupted vertical drop at 1,612 ft (491 m).

95% of Yosemite has been designated as wilderness, making it a haven for wildlife. In addition, over 225,000 acres (91,000 hectares) of the park is old-growth forest, having never been significantly altered by logging. The protected habitat, combined with the wide range of elevations, supports a wide array of animals. Over 400 species of vertebrates, including mammals, birds, reptiles, amphibians and fish live in the park, along with thousands of different plants.

Herbivores in the park include the commonly seen mule deer and golden-mantled ground squirrels, and less commonly seen animals like mountain beavers, pika, yellow-bellied marmots, white-tailed hares, and the rare Sierra Nevada bighorn sheep that are found only around Tioga Pass. Predators include black bears, mountain lions, coyotes, bobcat and gray fox. While once common, bear incidents have declined significantly in past years due to careful management, but be aware that while visitors are unlikely to see a bear, the animals are particularly active at night throughout the park, including in Yosemite Valley, and will seek out food sources that are available to them; heed all park regulations regarding storage of food items or items such as deodorants that have a smell that might interest a bear. Other animals found in the park include 17 species of bats, as well as over 150 species of birds such as great gray owls, spotted owls, white-headed woodpeckers, Steller's jays and northern goshawk. Reptiles are not common but include the mountain kingsnake and Gilbert's skink.

With elevations ranging from 1,800 ft (550 m) up to 13,000 ft (4,000 m) the park's vegetation zones range from scrub and chaparral communities at lower elevations to subalpine forests and alpine meadows at the higher elevations. Visitors will most commonly experience the park's extensive coniferous forest, but will also be drawn to the isolated groves of giant sequoias, the largest trees in the world. At elevations above 8,000 ft (2,400 m) beautiful subalpine meadows flower during July and August, while the treeline ends at 9,500 ft (2,900 m) and the vegetation is limited to hardy plants that bloom quickly during the few snow-free months.

Weather can change rapidly during all seasons of the year, and will also vary greatly with elevation. When visiting it is wise to pack for any season with clothing that can be layered, ready to peel off or add on as conditions dictate. Always include some kind of rain gear; the park receives most of its precipitation in the winter months, but storms are common during the transitional spring and fall seasons, and spectacular thunderstorms may occur during summer.

For Yosemite Valley and Wawona (subtract 10-20°F (5-10°C) for Tuolumne Meadows), average weather is as follows:

• Summer: Typically warm and dry, with occasional thunderstorms; temperatures from 50°F (10°C) to the low 90°F (30°C) range.
• Fall & Spring: Highly variable, with typical high temperatures ranging from 50-80°F (10-27°C), with lows from 30-40°F (-1 to 4°C). Rain is less likely early in fall/late in spring and rain or snow is likely late in fall/early in spring.
• Winter: Snowy, rainy, or (sometimes) even sunny days are possible, with highs ranging from 30-60°F (-1 to 16°C) and lows in the high 20°F (-4 to 0°C) range. Winter Storm Warnings indicate a significant storm is impending or occurring.

Warning: There are no gas/petrol stations in the Yosemite Valley!

There are four major entrances into the park. All of these routes are relatively winding mountain roads and appropriate time should be budgeted for them.

• State Route 120 from the west from Oakdale. This is the fastest route from locations west (Bay Area) and northwest (Sacramento). Route 120 is a bit steep, so RVs and trailers should consider Route 140 instead. In winter, snow makes the lower elevations of Route 140 more attractive.
• State Route 140 west from Mariposa and Merced. This route mostly travels up the Merced River Canyon into Yosemite Valley and is the most scenic western entrance. RV and tour bus traffic used to congest this road a bit too much in summer, but the Ferguson rockslide in 2006 has caused restrictions to be imposed that prevent vehicles longer than 45 ft (14 m). Highway 140 is now pleasantly less congested and the bridges afford an excellent view of the massive rock slide.
• State Route 41 north from Fresno and Los Angeles/Southern California. Be sure to fill your gas tank in Oakhurst (several stations along highway), or pay dearly as you get closer to the park. Many businesses (including two more gas stations) are on the first half mile of adjoining State Route 49 in Oakhurst.
• State Route 120 from the east (Tioga Pass Road) from Lee Vining and points east. This road is only open when free of snow (usually May - October) so check road conditions in advance.

A secondary entrance exists to Hetch Hetchy Reservoir exclusively (no Yosemite Valley access) off of State Route 120 from the west. It requires taking a side road near the main Route 120 west entrance of Yosemite. Hetch Hetchy has restricted hours for access due to security for the Reservoir.

During the snow season, usually November through March, snow chains may be required. Chain requirements are strictly enforced in Yosemite with potential fines being as much as $5,000, so chains should be carried during those months.

During summer months traffic becomes heavily congested in Yosemite Valley, and parking can be nearly impossible to find. Summer visitors to Yosemite Valley are therefore strongly encouraged to use the YARTS shuttle system (see below) to get into the park.

There are no landing strips within the park. Airports in surrounding communities include:

• 36.770931-119.7189611 Fresno Yosemite International Airport (FAT ^IATA), Fresno. About 1½ hours (by car) south of the park's entrance on Highway 41. Not a large airport, but by far the largest of the four airports in the San Joaquin Valley (also known as the Central Valley) west of Yosemite. Has flights to Dallas/Fort Worth (DFW ^IATA), Denver, Guadalajara (Mexico), Las Vegas, Los Angeles (LAX ^IATA), Phoenix, Chicago, Portland (OR), Salt Lake City, San Diego, San Francisco (SFO ^IATA), and Seattle-Tacoma. Has YARTS bus service to Yosemite during the summer months. (updated Dec 2019)
• 37.284722-120.5138892 Merced Airport (MCE ^IATA), Merced. About 2 hours (by car) from Yosemite Valley on Highway 140. Commuter flights from Los Angeles (LAX ^IATA), and Sacramento. To reach Yosemite, take the YARTS shuttle. (updated Dec 2019)
• 37.894167-121.2383333 Stockton Metropolitan Airport (SCK ^IATA), Stockton. Allegiant Air offers flights to Las Vegas, San Diego, and Phoenix, and United flies to Los Angeles. About 1 hr 45 min (by car) from the park's west entrance on Highway 120. (updated Dec 2019)

Bay Area airports including San Francisco International Airport (SFO ^IATA), Oakland International (OAK ^IATA), and San Jose International (SJC ^IATA) are much larger than any of the above airports and have more frequent flights to more destinations. Driving distance from the Bay Area is approximately four hours. However, landing at SFO requires crossing one of the San Francisco Bay bridges which are usually congested during the morning and evening rush hour. (Likewise for the return flight, and this direction includes a toll booth.) Sacramento International airport (SMF ^IATA), north of Sacramento, is another large airport option that is also about a four-hour drive from the park. Visitors arriving from the east may choose Reno/Tahoe International (RNO ^IATA) in Reno, which is about 3½ hours (by car) from the Tioga Pass Entrance (summer only). Combining a flight to a major airport with an Amtrak or Greyhound ride can be an affordable and scenic option.

Small private aircraft land at 37.510833-120.0394444 Mariposa-Yosemite Airport (RMY ^IATA) about 5 mi/8 km northwest of the town of Mariposa on State Route 49. There is no control tower, and car rentals in the area are very limited. The YARTS shuttle (see below) is another possibility. Park entrance is an additional 27 mi/44 km via State Route 140.

Amtrak offers service to Yosemite by means of a motorcoach bus that meets its San Joaquins trains in Merced. The San Joaquins provide several departures each day along its route from Bakersfield in the south, Sacramento in the north, and the San Francisco Bay Area in the west. With ample motorcoach connections to and from the trains, this train service serves most of the state, allowing quick and easy access to Merced from most places within the state. The trip to/from San Francisco will take 6+ hours by public transport, compared to 5 hours via car.

Many tour bus companies run tours from the Bay Area. Some will just take you to Yosemite Valley; others provide full tours to see the Giant Sequoias and/or Glacier Point.

The Yosemite Area Regional Transportation System (YARTS) offers reasonably-priced transportation into Yosemite Valley from locations east and west of the park including Highway 41 (Fresno, Oakhurst, Coarsegold), Highway 140 (Merced - where you can transfer to Amtrak trains to/from San Francisco, Mariposa, El Portal), Highway 120 (Sonora, Jamestown, Groveland) and Highway 120/395 on the east side of the Sierras (Lee Vining, Mammoth Lakes). Ticket price includes park admission, and adult tickets include a free ticket for one child 12 or under. Tickets can be purchased ahead of time or from the shuttle driver, and round-trip fares are between $7 (from El Portal) to $36 (from Mammoth Lakes) into Yosemite Valley; reduced fares are available to seniors, disabled individuals, and children 12 and under. When combined with the free shuttle service that operates within Yosemite Valley, YARTS can eliminate many hassles for summer visitors.

With most of the park visitors destined for Yosemite Valley, traffic and parking are significant problems during the busy summer season. As a result, while a car is a great way to tour the park, if visiting the Valley, taking YARTS and the shuttle bus may be a vastly better option. Be aware that the Tioga Pass Road and the road to Glacier Point are seasonal and close as soon as the first major snow falls. Other park roads may close during storms, but in general are always open. The speed limit in all areas of the park is fairly slow, and is strictly enforced by rangers with radar guns; the speed limits are for your own safety on the twisting mountain roads, as well as for the safety of pedestrians and the many animals that use the area.

The loop road through Yosemite Valley is now one-way. For many years this was a two-lane road, but motorists travelling slowly to admire the scenery often created a long backup of annoyed drivers, so the Park Service converted most of the roads in the valley into one-way roads to allow passing. As a result, when driving in the valley be aware that a wrong turn can send you on a one-way 5 mi (8.0 km) detour.

The one-way routing affects those entering from Oakdale on Hwy 120 the most. You will have to cross over to Southside Drive at the Pohono Bridge. Likewise upon leaving the park, those taking the south exit on Hwy 41 to Fresno also cross the Pohono Bridge, backtrack 1 mi (1.6 km), before turning right onto Wawona Road.

To limit traffic congestion the park service normally runs several free shuttle buses throughout the park (these are not the YARTS system):

• Yosemite Valley. Shuttles operate every 15 minutes from 7AM until 10PM in the eastern portion of Yosemite Valley year-round, stopping at or near all accommodations, shopping areas, and major sights.
• Badger Pass Bus. During the ski season a free bus travels twice daily between Yosemite Valley and the ski area.
• Tuolumne Meadows Shuttle Bus. During the summer season this bus provides access to points in and around Tuolumne Meadows.
• Tuolumne Meadows Hikers' Bus (fee charged). This bus travels in summer between Yosemite Valley and Tuolumne Meadows, dropping hikers off along the way. To guarantee seating tickets should be purchased one day in advance by calling ☏ +1 209 372-1240.
• Glacier Point Hikers' Bus (fee charged). This bus provides service between Yosemite Valley and Glacier Point, making stops along the way. To guarantee seating tickets should be purchased one day in advance by calling ☏ +1 209 372-1240.

The shuttle buses all have wheelchair lifts and tie-downs. Drivers provide assistance.

Yosemite Valley has a network of bicycle paths along its north and south sides. Bikes can be rented for the day at Curry Village & turn a thirty-minute walk into a five-minute ride.

Although the road network covers the most popular sights in Yosemite, the vast majority of the park's area can only be accessed using the park's network of trails. Trails including the John Muir Trail and the Pacific Crest Trail lead to areas outside of the park's north and south borders.

Yosemite Valley is the reason why Yosemite was America's first place set aside by the federal government for its scenic beauty. The cliffs rise around the valley at impossibly vertical angles, waterfalls tumble down unimpeded from a thousand feet (300 m) above, and the Merced River meanders aimlessly along the valley floor. The Valley is also one of the most accessible places in the park, with roads open year-round and plenty of amenities including lodging and food (but no gas stations). During summer months traffic can make the valley highly congested, so consider using the shuttle to cut down on stress.

Those entering the valley via Highway 41 will be treated to the spectacular viewpoint known as Tunnel View. Named for the tunnel that bores through the granite, the eastern side provides a dramatic view of Yosemite Valley with El Capitan on the left, Bridalveil Fall on the right and Half Dome in the center. Photographers should consider this area for pictures after storms, as many of the most famous pictures of the Valley have been taken from this spot as rough weather clears. There are two small parking lots that can get congested, so arrive early in the day if visiting during Summer to ensure a spot.

The sights in the valley include the granite monolith of Half Dome, a mountain that looks like it was split in two, leaving only a vertical face and rounded granite summit behind. In reality Half Dome was formed in the same way that many of Yosemite's granite formations were created - long ago an intrusion of magma deep underground solidified to form a massive granite block, and that block was eventually exposed to the surface via a combination of erosion and uplift. Glaciers that flowed through Yosemite did the rest, carving out the wide, U-shaped valleys that are bordered by sheer vertical walls. These same forces created the wall of El Capitan, a mecca for rock climbers and another of the Valley's famous formations.

Waterfalls in Yosemite Valley include Yosemite Falls, one of the highest waterfalls in the world at 2,425 ft (739 m). Bridalveil Fall is another easily accessible waterfall, while Nevada Fall and Vernal Fall can be reached by those willing to do some hiking. While some water flows over the waterfalls year-round, by mid-Summer flows are significantly diminished - plan on visiting in the Spring to see these waterfalls at their grandest. Yosemite is one of two places in the US – the other is Cumberland Falls State Resort Park – where "moonbows", or faint nighttime rainbow produced by the moon's light, can be seen. When the water is flowing and the moon is near the full, you may be able to see one, if you're in the right spot and have sharp eyes. https://www.yosemitemoonbow.com/ has predicted days, times, and locations for these special moments.

Wawona is the home to the historic Wawona Hotel, dating from the late nineteenth century. The Pioneer Yosemite History Center, a collection of historic buildings, is just over the covered bridge from the hotel. Wawona is accessible by car year-round.

The Mariposa Grove is the largest of the three giant sequoias groves in the park (the Merced Grove and Tuolumne Grove are the other two) and is home to over 500 mature trees. While not the tallest or oldest things on earth, by volume the giant sequoias are the largest living organism known to man. The grove is south of Wawona near the entrance station, with parking available in a lot located 2 mi (3.2 km) from the grove, and a shuttle bus available to bring visitors from the parking lot into the grove. Trails lead from the Lower Grove to the Upper Grove - traversing the entire route is a 3-4 mile (5-6 km) hike, depending on the paths chosen. Trees within a short walk of the lower parking area include the Grizzly Giant, a massive 1800 year old tree, and the California Tunnel tree, which was cut in 1895 to allow carriages to pass through. Further on, in the Upper Grove, is the Clothespin Tree, which has a natural tunnel in it created by fire that is large enough for a car to pass through, the Wawona Tunnel tree, another tree with a man-made tunnel in it that fell in 1969, and the Telescope Tree, a living tree that is hollow inside, allowing visitors to enter its trunk and stare upwards.

Glacier Point, an overlook with a commanding view of Yosemite Valley, Half Dome, Yosemite Falls, and Yosemite's high country, is generally regarded as the most spectacular viewpoint in the park. It is accessible by car from approximately late May through October or November. Driving time from Wawona and Yosemite Valley is about an hour, but during the busiest summer weekends delays of up to two hours are possible if the Glacier Point parking lot fills. From the parking lot a quarter mile long paved walkway leads to a viewpoint 3,214 ft (980 m) above the Yosemite Valley floor. From mid-December through March the road is usually closed, but cross-country skiers can experience this view after skiing 10.5 miles (17 km). The area is particularly popular late in the day to watch the light changing on Half Dome, and is also an excellent area for stargazing. Washburn Point, just south of Glacier Point, offers views of the southern side of Yosemite Valley.

Badger Pass is the oldest ski area in California, and is along the road to Glacier Point. The road to Badger Pass is plowed year round, and this area is the starting point for downhill skiing, cross-country skiing, and snowshoeing during the winter. During winter months a free shuttle runs twice a day from Yosemite Valley to Badger Pass.

The Tioga Road (Highway 120 East) is an amazingly scenic route through Yosemite's high country that crosses the park from west-to-east and provides access to the Eastern Sierra and Mono Lake. This road is closed in winter and usually opens to vehicles only from late May or early June through the first snowfall in November. It offers a 39 mi (63 km) scenic drive between Crane Flat and Tuolumne Meadows through forests and past meadows, lakes, and granite domes. Many turnouts offer broad and beautiful vistas. From Tioga Road all the way to the south of Mount Whitney, no other roads cross the High Sierra, making this the northern end of the largest contiguous roadless wilderness in the continental United States. The high point of the Tioga Road at Tioga Pass (elevation 9,943 ft (3,031 m)) is the only place in the park where visitors might encounter the endangered Sierra Nevada bighorn sheep.

Along the Tioga Road at 8,600 ft (2,600 m) elevation, Tuolumne Meadows is one of the largest high-elevation meadows in the Sierra Nevada. The Tuolumne River meanders across the meadow while rugged mountain peaks and glacially carved domes surround it. During the brief snow-free summer season the meadow is the site of a massive wildflower bloom, making this an excellent area for day hikes and photography.

Crane Flat is a pleasant forest and meadow area 16 mi (26 km) (30 minutes) from Yosemite Valley. Crane Flat is accessible by car all year. Bears can be spotted in the meadows in this area regularly, so keep your eyes open and don't block traffic if you see one!

The Tuolumne Grove has about two dozen mature giant sequoias and is on the Tioga Road just east of Crane Flat. Sequoias are only visible after a 1 mi (1.6 km) hike with 500 ft (150 m) of elevation loss. (The 1 mi (1.6 km) hike back to the parking lot gains 500 ft (150 m) and is strenuous.) The drive takes about 1½ hours from South Entrance. Parking is limited.

The Merced Grove is on the Big Oak Flat Road east of Big Oak Flat Entrance and is home to about two dozen mature giant sequoias. Sequoias are only visible after a 1½-mile hike with 500 ft (150 m) of elevation loss. (The 1½-mile hike back to the parking lot gains 500 ft (150 m) and is strenuous.) The drive takes about 1½ hours from South Entrance. Parking is extremely limited.

Until the completion of the O'Shaughnessy Dam in 1923, the Hetch Hetchy Valley was said to rival Yosemite Valley for beauty. The fight over the dam was a bitter battle between environmentalists including John Muir and the city of San Francisco, and efforts are still ongoing to remove the dam and restore the valley, though restoration of the habitat would likely take decades or more after the dam's removal. Today, the dam is used to deliver water from the Tuolumne River 167 mi (269 km) west to San Francisco. Even though Hetch Hetchy Valley is flooded, it is still home to spectacular scenery and is the starting point for many less-used wilderness trails. Although the road to Hetch Hetchy is open year-round, on a day-to-day basis it has restricted hours due to security for the reservoir. It may close periodically due to snow in winter and spring. Swimming and boating are not allowed in the reservoir.

The Grand Canyon of the Tuolumne lies upstream from Hetch Hetchy and is accessible to hikers. Hikers can also visit two of North America's largest waterfalls in the Hetch Hetchy Valley: Wapama Falls, at 1,700 ft (520 m), and Tueeulala Falls, at 840 ft (260 m).

Yosemite is one of the world's most spectacular hiking destinations, and all visitors should consider at least a short hike. The Vernal Fall trail is a short and rewarding trek for valley visitors, numerous trails in the high country along Route 120 are suitable for brief trips to see alpine lakes or granite domes, and the sequoia groves all offer the option of short hikes that can easily be extended. More adventurous and physically-fit hikers might consider the Half Dome trail or any of the park's backcountry trails. Prior to hiking check with rangers for trail conditions; snow and hazards from falling rock close many trails in winter, and the cables on the Half Dome trail are only up from late May through early October (ascending Half Dome when the cables are not erected is possible but is dangerous and strongly discouraged). No permits are required park-wide for day hikes, with the exception of the Half Dome Summit.

Yosemite Valley

edit

Many of the meadows have short trails, some of which are handicap accessible. For those staying in the valley, walking to get around is easy, scenic, and avoids the stresses of car travel in the valley.

• 37.745683-119.5936261 Lower Yosemite Fall (1 mi (1.6 km) loop), Starts at the Lower Yosemite Fall shuttle bus stop (#6). This flat, easy, paved one-mile loop trail leads to the base of Yosemite Fall and provides views of the waterfall along the way. During the spring the sound of the water is deafening, although it may be nearly dry by late summer. There is no parking at the trailhead, but there is a shuttle stop. The eastern part of the loop is wheelchair accessible. (updated Dec 2021)
• 37.716782-119.6509492 Bridalveil Fall (0.5 mi (0.80 km) round-trip), Starts from the Bridalveil Fall parking area. Another flat, easy, paved trail that leads to the bottom of the 620 ft (190 m) Bridalveil Fall. Parking is available at the trailhead. Despite being paved, the trail is not wheelchair accessible due to the grade (it ascends 80 ft (24 m) in elevation). The trailhead to this fall is on the Southside Dr, so it's best to visit it on your way to the Valley. (updated Dec 2021)
• 37.74851-119.58733 Cook's Meadow Loop (1 mi (1.6 km) loop). This flat, easy loop trail meanders through the meadow across from the visitor center and near the Lower Yosemite Fall trail, offering excellent views of Half Dome, Yosemite Fall, Glacier Point and Sentinel Dome. From the visitor center, walk west along the bicycle path toward Lower Yosemite Fall. At shuttle stop #6, cross the street and follow the bike path, bearing left as the path forks. At Sentinel Bridge parking area (shuttle stop #11), walk out onto the bridge to enjoy a classic view of Half Dome before returning to the parking area. Follow the boardwalk back across the meadow, cross the two streets, and turn right to return to the visitor center. (updated Dec 2021)
• 37.739428-119.5598624 Mirror Lake/Meadow (2 mi (3.2 km) to Mirror Lake, 5 mi (8.0 km) around the lake), Starts from the Mirror Lake trailhead shuttle bus stop (#17). The first mile of the trail follows a paved service road and eventually leads to what is a large pond in spring and a meadow the rest of the year. When it contains water the lake reflects Half Dome, but even when the lake is dry the meadow still offers scenic views. Those who are interested can also hike around the lake bed and along Tenaya Creek. (updated Dec 2021)
• Valley Floor Loop (6.5 mi (10.5 km) round-trip with cutoff, 13 mi (21 km) without). The loop trail around Yosemite Valley can be hiked in pieces or in full as it travels through meadows, forests, and beside the Merced River, offering great views of Yosemite Valley. Following the road in places, the trail can be shortened by crossing the bridge just east of El Capitan Meadow. The majority of this trail network is wheelchair accessible with the exception of the Superintendent's Bridge and a steep section near Housekeeping Camp. (updated Dec 2021)
• 37.7274-119.5445 Vernal Fall (Mist Trail) (2.4 mi (3.9 km) round-trip), Starts from the Happy Isles shuttle bus stop (#16). This trail gradually gains 400 ft (120 m) of elevation along the Merced River by the time it reaches a footbridge offering an excellent view of the 317 ft (97 m) high Vernal Fall. From the footbridge the trail quickly gains another 600 ft (180 m) of elevation as it traverses steep and often slippery granite steps to the top of the waterfall, but the view is hugely impressive and worth the exertion. The Mist Trail is one of the busiest trails in the park during the high season––returning visitors might want to consider a hike outside the valley. From the top of Vernal Fall hikers can continue on to Nevada Fall. (updated Dec 2021)
• 37.725278-119.5327786 Nevada Fall (Mist Trail) (5.4 mi (8.7 km) round-trip), Starts from the Happy Isles shuttle bus stop. Nevada Fall is a 594 ft (181 m) waterfall 1.5 mi (2.4 km) beyond Vernal Fall. The trail from the top of Vernal Fall is relatively easy and passes through a pleasant stretch of the Merced river with several pools (beware of currents!) surrounded by impressive granite cliffs before leading up a steep series of steps to the top of the waterfall. The John Muir trail is a more gradual ascent that can be undertaken from the junction near the Vernal Fall footbridge, but those who choose that route will forgo the view from the top of Vernal Fall as well as the scenery along the Merced River; consider ascending on the Mist Trail and descending on the John Muir trail if you want to enjoy the scenery but limit the trauma to your joints. The total elevation gain from the Happy Isles trailhead to the top of Nevada Fall is 2,000 ft (610 m). (updated Dec 2021)
• 37.726889-119.5733897 Panorama Trail (8.5 mi (13.7 km) one-way), Starts from Glacier Point. The Panorama Trail offers panoramic views of the valley and passes by three of Yosemite's most impressive waterfalls, although you'll likely only see two of them; while Vernal Falls and Nevada Falls are easily viewed, there is no viewpoint of 370 ft (110 m) tall Illilouette Fall despite the fact that the trail crosses Illilouette Creek only a short distance from the top of the waterfall. Panorama Point is accessible via an easily-missed 300 ft (91 m) unmarked side trail that can be found 0.5 mi (0.80 km) from the Illilouette Creek bridge and is a detour that should not be skipped. From late May/early June through October, a fee-based hikers bus will take you up to Glacier Point, where you can then hike two downhill miles to Illilouette Creek, ascend 700 ft (210 m) in elevation over 1.5 mi (2.4 km), and eventually descend on either the Mist Trail or the John Muir Trail back down to the valley floor, ending at Happy Isles. (updated Dec 2021)
• 37.7325-119.5878 Four Mile Trail to Glacier Point (4.8 mi (7.7 km) one-way). The trail follows switchbacks from Glacier Point and offers spectacular views up and down Yosemite Valley. Hikers can take the shuttle bus from the valley to Glacier Point and then hike down, or those looking for an extremely strenuous hike can ascend starting from the Four Mile Trailhead just west of Swinging Bridge picnic area. Visitors interested in a long day hike can make a loop on this trail with the Panorama Trail. (updated Dec 2021)
• 37.742471-119.6022319 Upper Yosemite Fall (7.2 mi (11.6 km) round-trip), Starts near the Camp 4 shuttle bus stop. One of the oldest trails in the park, the Yosemite Fall trail was built back in 1873 and ascends 2,700 ft (820 m) from the base of the 2,425 ft (739 m) high Yosemite Falls all the way to the top of the waterfall. The first 1 mi (1.6 km) ascends 1,000 ft (300 m) steeply to Columbia Rock, which offers exceptional views of the valley and Half Dome. A less strenuous 0.5 mi (0.80 km) further along the trail offers views of the upper Yosemite Fall. The second half of the trail is equally strenuous, but the incredible views reward those who choose to continue. In summer bring plenty of water and begin hiking early as the trail becomes extremely hot and dusty. (updated Dec 2021)
• 37.746-119.53316710 Half Dome (17 mi (27 km) round-trip), Starts at the Happy Isles shuttle bus stop. One of the most spectacular trails in the world, the Half Dome trail travels past Vernal Fall, and Nevada Fall, and then continues rising through a pine forest before opening up near the summit of Half Dome. The final mile is a grueling trek up granite steps, followed by wire cables that lead up the steep ascent to the top of Half Dome. Hikers should bring leather work gloves to protect their hands from the cables; some gloves are often available in a pile at the bottom of the cables. While it is possible to ascend Half Dome while the cables are down (between approximately October 15 and May 15), hikers do so at their own risk. Views and scenery are unforgettable, but hikers should be aware that the final climb up the back side of Half Dome via the cables can be exhausting and, for those with even a mild fear of heights, frightening. While the majority of the trail is accessible without a permit, an $8 permit is required to traverse the final stretch of the trail beyond the base of the Half Dome subdome. 300 permits are available each day (approximately 225 to hikers and 75 to backpackers), with rangers stationed on the trail to turn away hikers without permits. Permits can be obtained in advance via a pre-season lottery (apply online between March 1 and March 31, permits issued in mid-April, an additional online application fee of $4.50 applies), and approximately 50 permits are made available in an evening lottery two days prior to the hiking date.

The Soda Springs are protected within a log enclosure. Carbonated water bubbles up through the ground, but drinking the water is not recommended due to possible surface contamination. Further along the trail is the historic Parson's Memorial Lodge, which offers exhibits. 
• 37.878463-119.33889917 Dog Lake (2.8 mi (4.5 km) round-trip), Starts at the Dog Lake/John Muir Trail parking area.

Enjoy fishing and picnicking from this high country lake. 
• 37.878463-119.33889918 Lembert Dome (2.8 mi (4.5 km) round-trip), Begins at the Dog Lake/John Muir Trail parking area. A strenuous hike that goes up steeply for 0.75 mi (1.21 km) to a signed junction. The trail to the left goes to the top of Lembert Dome. Expect a spectacular panoramic view of Tuolumne Meadows, Cathedral Peak, and Unicorn Peak. The top of the dome can be windy and quite a bit cooler than down below. 
• 37.878463-119.33889919 Dog Lake and Lembert Dome (5.0 (8 km) mi loop). These two hikes can be combined in a loop that delivers some of the best scenery from any five-mile hike in the park. Do the lake first, before you get tired from the dome climb. 
• 37.881317-119.35863320 Glen Aulin (11 mi (18 km) round-trip), Starts from the road near Tuolumne Meadows Stables.

There are restrooms there. 

• Cathedral Lakes (7 mi (11 km) round-trip). From the Cathedral Lakes Trailhead the trail climbs steadily 1,000 ft (300 m) to Upper Cathedral Lake. Near the top, it passes a spur trail to Lower Cathedral Lake. 
• John Muir Trail through Lyell Canyon (8 mi (13 km) one-way). From the Dog Lake/John Muir Trail parking area this relatively flat trail (only 200 ft (61 m) elevation gain over 8 mi (13 km)) wanders through Lyell Canyon, mostly alongside the Lyell Fork of the Tuolumne River. 
• Mono Pass (8 mi (13 km)), Starts at the Mono Pass Trailhead (6 mi (9.7 km) east of Tuolumne Meadows). A moderately difficult trail that climbs gently at first (1,000 ft (300 m) elevation gain) to a junction with Spillway Lake. The left fork then steeply climbs to Mono Pass, at 10,500 ft (3,200 m). From the pass, Upper Sardine Lake is another 0.75 mi (1.21 km) down the pass to the east. 
• Gaylor Lakes (2 mi (3.2 km)), Starts from the Gaylor Lakes Trailhead (at the Tioga Pass Entrance Station). A strenuous trail that climbs steeply in the first 0.5 mi (0.80 km) (1,000 ft (300 m) elevation gain) to a ridge with views to both sides. At the ridge, the trail drops 200 ft (61 m) to a lake and meadows, which can be explored with side trails. 
• Vogelsang High Sierra Camp, Lake, and Pass (15.8 mi (25.4 km)), Starts from the Dog Lake/John Muir Trail parking area. The trail's first 2 mi (3.2 km), along the John Muir Trail, are relatively level. The Rafferty Creek Trail then splits off and begins a 1,200 ft (370 m) ascent to Tuolumne Pass, followed by a 160 ft (49 m) climb to the High Sierra Camp. You can continue to Vogelsang Lake (0.5 mi (0.80 km) further) and spectacular Vogelsang Pass (1.5 mi (2.4 km) further). 

The Valley also offers some of the most challenging and spectacular rock climbing in North America, with vertical faces 3,000 ft (910 m) and more feet tall. Wilderness permits are not required for nights spent on a wall, but it is illegal to camp at the base of any wall in Yosemite Valley. Additional regulations:

1. Do not litter or leave anything behind, including food or water "for future parties". Pick up any litter you see, including tape wads and cigarette butts.
2. Don't leave fixed ropes as permanent fixtures on approaches and descents. These are considered abandoned property and will be removed.
3. Minimize erosion on your approach and descent. If an obvious main trail has been created, use it. Avoid pushing soil downhill and avoid walking on vegetation whenever possible.
4. If an unplanned bivouac is necessary on a summit, fires are allowed only in an existing fire ring and building a new windbreak is prohibited. Make sure your fire is completely out before you leave.
5. Clean extra, rotting slings off anchors when you descend. Bring earth-toned slings to leave on anchors.
6. Check the Camp 4 Kiosk or the Mountain Shop for the current peregrine falcon closures.
7. Minimize the impact of first ascents by choosing routes that minimize erosion, bolts, and loss of vegetation. "Gardening", e.g. killing plants, is illegal in Yosemite. Motorized drills are prohibited.

Swimming is allowed in most bodies of water in the park, but is either prohibited or strongly discouraged near waterfalls due to the extreme danger of being swept away - to cite just one tragic example, as of 2010 the total number of people who have died after underestimating currents and being swept over Vernal Fall stands at seventeen. Other places where swimming is prohibited include the following:

• Hetch Hetchy Reservoir, and within one mile upstream along any tributary (e.g., Rancheria Falls).
• Dana Fork of the Tuolumne River
• Emerald Pool and Silver Apron (above Vernal Fall)
• Lake Eleanor Reservoir (when posted)

Rafting is also allowed on the South Fork of the Merced River below Swinging Bridge (in Wawona).

Fishing is allowed in streams and rivers from the last Saturday in April through November 15, with the exception of Frog Creek near Lake Eleanor, where fishing season does not open until June 15 to protect spawning rainbow trout. Fishing is allowed in lakes and reservoirs year-round. A valid California fishing license is required for anyone aged 16 or older. Fishing supplies, including fishing licenses, are available at the Yosemite Village Sport Shop and at the general stores in Wawona and Tuolumne Meadows.

Downhill skiing options include ten runs at Badger Pass. The majority of these runs are for beginners and moderate skiers, so thrill seekers may wish to ski elsewhere. Both downhill and cross-country lessons are available. Due to NPS regulations in place to ensure the area remains as natural as possible, the Badger area has no artificially-lighted skiing and cannot make its own snow. Lift tickets cost $5.50 for a single run or $48.50 for a full-day ticket. (updated Mar 2015)

Camping is by far the cheapest way of staying within the park, but campgrounds fill quickly during summer months and may require making reservations months in advance. Reservations can be made through the National Park Service from 7AM-7PM Pacific time, or by calling ☏ +1-877-444-6777 or ☏ +1 518-885-3639 from outside the United States. Written reservation requests can be made by including desired location, type of equipment you will be camping in (i.e., tent, RV, etc.), as well as method of payment. Send written requests to NPRS, P.O. Box 1600, Cumberland, MD 21502.

All campgrounds offer bear-safe food storage containers, tap water (except where noted), and flush toilets. Pay showers and laundry are in Curry Village in Yosemite Valley. During summer, showers are also available afternoons at Tuolumne Meadows Lodge.

For backpackers, North Pines in Yosemite Valley and the Tuolumne Meadows campground both have "backpacker camps". These are walk-in sites offered for people with valid wilderness permits to stay the night before and the night after their backcountry trips. For more information contact the Yosemite Valley Wilderness Center or any park campground office.

Backcountry permits are free and are required year-round for all overnight trips into Yosemite's wilderness. Wilderness areas operate under a quota system that limits the number of people who may begin overnight hikes from each trailhead, each day. While permits may be reserved for $5 per party plus $5 per person, at least 40% of each trailhead quota is available on a first-come first-served basis the day of, or one day prior to, the beginning of your trip.

Permits can be obtained in person from the wilderness stations in Yosemite Village, Big Oak Flat, Tuolumne Meadows, Badger Pass, Hetch Hetchy and Wawona. In addition, permits can be reserved up to 24 weeks in advance for a fee. There are three ways to reserve a wilderness permit, and forms for advance reservations can be found on the Yosemite wilderness permit web site:

1. By fax. A fax sent to ☏ +1 209-372-0739 is the park service's preferred method of obtaining a wilderness permit. Forms can be found on the Yosemite wilderness permit web site. Faxes received before 7:30AM are processed before phone calls.
2. By phone. Reservations for summer trips are accepted from 2 days to up to 24 weeks in advance by calling ☏ +1 209-372-0740. Phones are staffed M-F 8:30AM-4PM, with extended hours from Memorial Day through Labor Day (M-F 8AM-5PM, Sa 9AM-4PM). You must know your entry and exit trailheads prior to calling.
3. By mail. Reservation requests for summer trips are accepted from 2 weeks to 24 weeks in advance by writing to Wilderness Permits, PO Box 545, Yosemite, CA, 95389. See Yosemite's web site for the reservation form to include with written requests. If your requested trailhead and dates are available, you will receive a confirmation letter in the mail. A payment method must be provided with all written requests.

All backcountry campers are expected to leave the wilderness in the same condition as they find it; this means no trash, fire scars, or other evidence of a visit should be left behind. Backcountry campsites must be at least four trail miles from Tuolumne Meadows, Yosemite Valley, Glacier Point, Hetch Hetchy or Wawona, or at least one trail mile from any road. Groups are limited in size to 15 people, including guides and small children. Pets, weapons, bicycles, strollers, and mechanized vehicles of any kind are not allowed in the wilderness areas, while fires are only allowed in existing fire circles, and are not allowed above 9,600 ft (2,900 m) elevation.

Bear canisters are required in all areas of the Park and highly recommended in areas close to Yosemite's borders. These canisters must be used for food storage, as well as for storing scented toiletries such as soap, deodorant and toothpaste, and should be stashed at least 100 m from your campsite. Canisters can be rented from the ranger station where you pick up your backcountry permit for $5, good for up to two weeks. Bear canisters are not just to protect hikers' food––they protect bears. There is no good excuse for conditioning bears to rely on human food.

• 37.74859-119.582965 Yosemite Medical Clinic, 9000 Ahwahnee Dr (Yosemite Valley), ☏ +1 209 372-4637. Drop-in and urgent care May-Sep: daily 9AM-7PM; Oct-Apr: M-F 9AM-5PM.

Over the years the park's bears have become accustomed to scavenging trash and food left out by humans, and will even break into cars and tents to get it. While not the larger grizzly bears that once roamed California, black bears are strong enough to tear a door off of a car with ease. Luckily they usually prefer to avoid humans, so they'll most likely do their work on vehicles left at trailheads or in parking lots. Prevention is remarkably simple: never leave food or scented items (deodorant, air fresheners) in your car or bring them into your tent. Heed this advice! Leaving even just a tube of toothpaste or empty food wrappers in a car may result in thousands of dollars of damage to your vehicle should a bear choose to investigate the smell! Bear-resistant storage units are provided at park campgrounds and overnight parking areas: use them.

To avoid bear encounters while hiking, make noise so that the animal knows you are coming. This approach will also help to avoid encounters with mountain lions, which also inhabit the park. Other animals, such as the herds of deer which can be found in the park's meadows, can be equally dangerous; a young boy was killed by a deer in Yosemite Valley several years ago. Give all animals their space, and never feed any park wildlife.

Yosemite Valley Lodge (and possibly other accommodation areas) has no outside lighting. This is to reduce light pollution and allow the stars to shine down. If moving about the area at night (even to go to the reception office or restaurant) ensure that you have a flashlight (torch), as walking in the dark can be quite hazardous. In general, avoid long hikes after dark.

Other natural dangers in the park come from the weather. Hypothermia can be a concern at higher elevations where temperatures can drop below freezing throughout the year. Dress in layers, and be prepared for storms and rapid changes in temperature. When storms are approaching avoid open areas such as the summits of the park's many granite domes; lightning strikes these areas regularly. If a storm does approach, get off of high, open ground. When hiking wear sturdy footwear and drink plenty of water - if you are thirsty that is an early sign of dehydration. Be aware that the sun can be intense at higher elevations and when reflected off of snow, so sunscreen is important. In the winter, take the weather term "Winter Storm Warning" very seriously as it means a significant storm is definitely coming.

Yosemite, because of its size, exposure, and cliffs, can be dangerous to those who fail to exercise basic precautions. While the park has amenities to aid tourists, Yosemite is huge and you can easily find yourself hours' drive away from potable water, emergency services, or a cell signal. Always do your homework before any hike. Remember to follow the basic safety guidelines for hiking:

• Understand the details of where you are going and plan ahead of time
• Always bring enough food/water to last you longer than you expect to be on the trail and remember park amenities may be hours away––and even if you get to them, they may have long wait times at the high season.
• Don't camp in the backcountry if you don't know what you're doing.
• Set a time to turn around and never stay on a trail past sunset if you don't have access to heat and light.
• Tell someone where you are going––if you don't, no one will know where to find you.

Hikers should follow all posted signs - if a trail is closed due to ice, landslide, or some other reason do not ignore the closure as doing so endangers both the hiker and any area that must be traversed to go around the closure. On the Half Dome trail, hikers should always remain inside the cables for their ascent and descent. Hikers died on this section of trail in Summer 2009.

The park's waterfalls pose another potential hazard. Do not attempt to get close to the waterfalls, especially in the spring. This includes swimming above the waterfalls at a distance of less than 1 mile (about 1.6 km). The force of the water will easily sweep a person off their feet and over the falls, even if it appears to be flowing slowly. Being swept over any of Yosemite's waterfalls is invariably fatal. Even if you see other people bathing in the pools above certain water falls––and you will––do not get into the water.

The greatest danger in the park comes from the thousands of park visitors. Petty thieves and traffic accidents are two issues to be aware of. Follow park speed limits, lock your vehicle, and be aware of your belongings, especially in Yosemite Valley. Violent crime is extremely rare in Yosemite, but given the numbers of people that visit you should expect that a few unsavory characters will be visiting too.

The National Park Service provides the primary law enforcement and fire protection in the park. NPS is supplemented by Aramark Security, who handle a number of calls for service on Aramark land assignments. Aramark Fire is paged out along with NPS Fire, and handles a large number of calls in Yosemite Valley.

Lost and found

There are two major Lost and Found operations in Yosemite. One is run by the National Park Service. It can be reached at ☏ +1 209-379-1001. The other is run by Aramark, and can be reached at ☏ +1 209-372-4357. They coordinate as best as possible, considering they are a half-hour away from each other. They process thousands of items each year and surprisingly get a number of items back to the rightful owner. Because of the thousands of items lost or found, generally, you will not get a return call unless your item has been found and turned in correctly.

Items that are found that cannot be returned to the owner are generally turned over to recognized charities. So, if you don't get your item back, and if it is turned in by the finder, at least you can rest easy that it will eventually go to a good cause.
