The Simms
A Simm is a hill in England, Wales or Scotland over 600m high with a drop of at least 30 metres all round. Simm is an acronym
for Six-hundred Metre Mountain. The Irish and Isle of Man Simms are also listed on this website.
A Subsimm is a hill which just fails (by up to 10m) to qualify on the drop rule, i.e. over 600m
with 20-29m drop.
