Description
The entrance is tight for the first few 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.
