Access
Follow the left-hand bank of the River Mellte downstream from the Porth-yr-Ogof resurgence until it flows through a small gorge. The cave is situated in this gorge on the left. A small stream issues from the cave and the entrance is just above.
Description
The entrance is 3m from the water's edge and is 1m x 0.5m high and drops into a very narrow stream channel, tight and difficult in parts. It is 45m long and the innermost parts are well decorated, preventing further exploration.
