Great Douk Cave
Great Douk Cave is a shallow cave system lying beneath the limestone bench of Ingleborough in Chapel-le-Dale, North Yorkshire, England. It is popular with beginners and escorted groups, as it offers straightforward caving, and it is possible to follow the cave from where a stream emerges at a small waterfall to a second entrance close to where it sinks 600 yards (549 m) further up the hill. It lies within the Ingleborough Site of Special Scientific Interest.
