A large open tree-lined pothole on the north side of the Eyam-Foolow road, with a stream falling into it.
Cavers covered by the BCA insurance scheme are welcome to visit the cave at any time, but cars must be parked in the car park, do not block the track at any time.
See the DCA website for competition details.
In extreme flood the entrance passage sumps. Do not descend if water is backing up significantly in the shakehole. A very loose cave in places, and rescue would be almost impossible through the tight entrance passages.
