Summary of site:
This is a complex, convoluted cave with the Sruh Croppa River (that sinks into its own bed at Cat's Hole) flowing at its deepest level. A tight, 4m descent through boulders ends at a 5m drop (avoided by a lateral course across a slope of mud and boulders to the river). Downstream the river zigzags over a length of 80m of spacious passage, varying in width from 5-20m, before sumping in a jumble of boulders which have yet to be dived.
In the upstream direction a crawl though more boulders emerges in a chamber floored by fallen blocks. Crawls from this chamber lead to a rift and to the west narrow passages and crawls give a glimpse into Cat's Hole (but without a way through).
