Active Cave
Access The cave lies in the floor of Black Rock Quarry and is in the process of being quarried away. Permission to visit the site should be sought from the quarry Manager (1980). A stream runs across the quarry floor from Ogof Rhaeadr Ddu and sinks in the cave.
Description The small entrance leads into an active stream passage. Upstream, the cave becomes too tight after the waterfall. Downstream leads to another waterfall and two chambers. The water emerges in Pylon cave.
