This is an underground creek underneath the Napier Ranges in the Western Kimberley. It is famous for being the hideout for Jandamarra (Pigeon), the leader of a group of Aborigines who in the late 1800’s where resisting the invasion of their land. They captured stock and were involved in sieges killing white settlers. This cave (hardly visible from the surrounding range) is said to have been his ideout for a number or years. He was killed in a police raid in 1897.
The tunnel itself in 750 metres long and is collapsed in the middle letting in natural light. You can walk from one end to the other but get wet feet!
