Dunderhole

Bishops Wood, Ruardean.

The cave is mostly crawling following the dip of the rock. A 30cm bedding leads to a 25m excavated crawl over pebbles through two right angle bends and a low squeeze. The stream enters from an inlet and leads to 50m of generally small passage with two ducks and eventually becomes too tight to follow.

Alternate Names: Dunderhole Farm Swallet

Notes: Access: From the farmer at Dunderhole Farm, but note that the farm is leased from the Bishopswood Estate. Ensure that you specify that you are going underground.

WARNING: Where the stream enters before Duck One it may be necessary to unblock the passage by removing accumulated debris. The cave is tight, the squeeze being a nutmeg grater. There are only four places to turn around and blocking by fellow cavers can be a 

problem.
