South Wales Caves

Ogof Clogwyn is an interesting and easy cave that is popular with novices and outdoor centres. The cave is located about 400m upstream from the Devil's Bridge in the Clydach Gorge (map). A small waterfall cascades out of the main entrance 1.5m up in the cliff face. The cave consists predominently of a single stream passage with some fine phreatic shelving that leads to a low silted sump. Several small crawls give access to a couple of additional smaller entrances in the cliff face where the cave is located.
