White Lady Cave

↓ Further information

White Lady Cave starts as an impressive section of passage until after a short distance the sump is encountered. The passages beyond this sump can sometimes be visited from an inlet in the bottom of Cwm Pwll Y Rhyd during long dry summer periods.

The cave was first recorded by T.A.J. Braithwaite in Caves and Caving Volume 1 1938. The cave takes it's name from a white boss and stalagmite that resembles a seated lady.
The cave is located in the Nedd Fechan valley downstream of Bridge Cave. Visit Blaen Nedd Isaf Farm first to obtain permission. A parking area is available beside Bridge Cave. The river is followed downstream past Bridge Cave to the dry river bed, this is followed through the gorge section to a 2m climb down. Below the climb, to the right is the obvious entrance to White Lady Cave.

Permission to visit the cave must be obtained from Blaen Nedd Isaf farm, where a one pound per person trespass fee will be charged.
At the bottom of the short climb down in the gorge the impressive 5m wide entrance is seen immediately on the right. A large pool of deep water is found immediately inside the entrance which can be passed by keeping to the right hand wall. Beyond the entrance pools the height of the passage increases and the water becomes less deep. After a short distance the sump pool is reached that marks the end of the cave for the non diver. Beyond the sump are about 200m of low passages that are accessible to divers or in long dry summer periods can be accessed via a passage at the bottom of Cwm Pwll Y Rhyd. Just before the sump pool is reached is a balcony on the right hand side. A short climb up here reaches some calcite flows and beyond is a window that acts as a vantage point above the central section of the main passage. Heading back towards the sump on the left hand side of the passage is a second balcony, in this case climbing up to it reveals a smaller passage that can be followed back to a second entrance. This passage contains some fine gour pools and calcite formations before a deep pool with a duck to the left is encountered. Through the duck leads to the final section of this passage and the second entrance slightly higher than the main entrance and a few metres further downstream.
No tackle is required.
