Access On the road from Pont Nedd-Fechan to Ystradfellte turn off on Gwaen Bryn-Bwch to the fenced road and go for 1.5 miles to Pont Cwm Pwll-y-rhyd. Cross the bridge and go North for 180m. Cross the river to a limestone exposure on the opposite bank. The entrance is in this at river bank level.
Permission should be sought from Blaen Nedd Isaf farm. 
Description The entrance is tight for the first mew metres 1m x 0.5m and lower than the riverbed level. It takes some water all the time. The entrance passage is not easy and is liable to flood very easily. The cave is at least 8km long and contains many sumps and fine passages and chambers. It joins up via a sump with Bridge Cave whence it was first discovered. Care must be taken in Bouncing Boulder Chamber. It only takes part of the Nedd Fechan water here but joins up with the rest of the water and goes towards the Mellte It is reputed that Bridge Cave water reappears at and near Pwlldu.
