About this park
At Dimalurru (Tunnel Creek) water has carved a large tunnel through the limestone of the Napier Range. The tunnel is up to 20m high and 15m wide in some parts! 350 million years ago this was part of an ocean reef system.
There is a Kimberley feel all-around. Sunlight arcs onto the cathedral-like cavern with a sense of mystery. Adding to the spectacle, large stalactite rock formations hang from the walls.
A deep history, as well as beauty exists here. It was used as a hideout late last century by the Aboriginal leader Jandamarra who was killed outside its entrance in 1897.
Take a walk through the 750m tunnel which takes you from one side of the Napier Range to the other. Keep your eye out for the many bat species and freshwater crocodiles that live in the cave. The roof has collapsed through to the top of the range near the centre of the tunnel. Take a torch, wear sneakers and be prepared to get wet and possibly cold and always let someone know where you are.
Day trips to Dimalurru (Tunnel Creek) operate from Derby, Fitzroy Crossing and Broome and often include a visit to Bandilngan (Windjana) Gorge.
You’ll never forget a walk into the tunnel of surprises. It's Crocodile Dundee and Indiana Jones all in one spot!
Please respect any Aboriginal paintings by not touching the art works.
