Peak Cavern

Peak District

Castleton's most convenient cave is easily reached by a pretty streamside 250m walk south of the village centre. It has the largest natural cave entrance in England, known (not so prettily) as the Devil's Arse. Dramatic limestone formations are lit with fibre-optic cables.
