Dragon Age Inquisition: Coracavus in The Western Approach Dragon Age: Inquisition Guide

Above, you can find the map of the Coracavus ruins, which you can access after you get to the Northern part of the Western Approach. You visit the ruins during The Trouble with Darkspawn side quest. Here, you encounter many opponents, but you also find lots of valuable items here. Therefore, it is a good idea to keep an eye out for them, while exploring the area (some of the places need to be broken into).
