The Hope valley around Castleton from Mam Tor looking east...
...with Castleton on the right, the south side of the valley. The entrance to Peak Cavern is in the Hill below marked by trees and bushes.
From Castleton it is just a short walk along a brook.
The entrance is a huge portal below a high limestone cliff. The roof of the first part of the cave collapsed and formed a gorge leading to todays entrance.
The first chamber contains the remains of a rope-making industry.
A look back shows the enourmous entrance.
