Location

The simplest, but not shortest way to reach this cave is to cross Devils Bridge in the Clydach Gorge, then climb up the 100 steps till the path ends by the side of a house. Turn right and continue along the lane until you go past a cottage with boarded up windows on the right. Just past the cottage a track descends into the gorge past an information board. Continue along the track and down some wooden steps put there to help you. The track becomes a ledge with cliff to your left and a drop into the river on your right. Very soon you come to the main entrance of Ogof Clogwyn from which a small stream issues. The entrance is about 1.5 metres up the cliff face.

Description

An interesting cave which contains some fine examples of phreatic rock shelving. It is also a good cave for beginners. The entrance leads directly to an active stream passage with some fine rock shelves. The passage is high, wide and roomy. The water is quite deep in places but is easily traversed over using the shelves. One continues past passages that lead to two very tight entrances. The passage then turns 90 degrees left, continues for about 30m then turns left and continues 10m. After another 15m there is a 90 degree right hand turn. At this point a fallen boulder allows one to climb up into a high level rift passage on the left in the corner.

If one continues high in the rift, after about 50m daylight can be seen through a narrow crack. To the right one can enter a small chamber which soon ends.

By staying low at the start of the high level rift one can enter a crawl on the left which leads to a hole in the roof of the main streamway, one can easily climb down and can see the second of the tight entrances at this point.

Continuing along the main passage from the fallen boulder the passage continues for about 50m, where there is a crawl to the right that soon ends at a small sump. Continuing along the main passage, the roof gradually lowers to meet the water at a terminal sump. This sump has been dived for 30m

History

The cave has probably been known for a long time but the first recorded exploration was by the SWCC. Survey in CSS Records (19) 1992.
