Tunnel Creek National Park is Western Australia's oldest cave system.
Part of the same ancient Devonian reef system as Windjana Gorge and Geike Gorge, the cave has been carved out by the waters of Tunnel Creek flowing beneath the Napier Range.
You can walk 750 metres into the tunnel, wading through freshwater pools. The cave features many beautiful formations, including stalactites and stalagmites, and is also home to a variety of bats, olive pythons and freshwater crocodiles. To experience the cave, take a reliable torch, wear old sneakers and be prepared to get wet – the water is mainly just over knee height but can be higher.
Tunnel Creek is a site of cultural significance for the local Bunuba people, and you can visit the cave system with a cultural guide to gain insight on the spiritual significance of the area.
The Bunuba leader Jandamarra frequented the area around Windjana Gorge and Tunnel Creek, and he died at the entrance to Tunnel Creek on 1 April 1897.
Access to the park is via unsealed roads, approximately 35 kilometres southeast of Windjana Gorge National Park or 90 kilometres from Fitzroy Crossing. Tunnel Creek National Park is a day use area only, with facilities limited to toilets and an information shelter. No overnight camping is permitted and access is limited to the dry season only.
A wide range of day and extended tours operate from Fitzroy Crossing, Derby and Broome which include both Tunnel Creek and Windjana Gorge.
