Welsh 3000s

Fifteen summits in Eryri stand above 3,000 feet, and walking all of them inside 24 hours is one of the hardest things you can do in Wales without a rope. Most people take it in pieces instead, which is no less worth marking.

Yr Wyddfa, Crib Goch, Glyder Fawr, Tryfan — the last of which is the only mountain in Wales whose summit cannot be reached without using your hands. Welsh names first, because they came first.
