Description First recorded exploration by the Morgan brothers in 1912,
The river cave can be followed for 120 metres to a sump. The show cave is 520 metres long and leads to a series of four lakes beyond which is a complex series of passages and chambers ending in a long crawl. In 1966 a major extension to the cave was discovered some one mile in length. Two further extensions were subsequently discovered giving the cave a length of over 9 miles. The old cave and first part of the new extensions run in a SW direction, the known passages then running north.
