Tunnel Creek - WA

Tunnel Creek National Park covers 91 hectares, however access is limited to this small day use area with facilities limited to toilets and an information shelter. Located 35km south of Windjana Gorge, the Tunnel Cave is the main attraction, and is Western Australia's oldest cave system. This underground cave/tunnel has been eroded beneath the limestone range by Tunnel Creek and is about 750m long and up to 12m high, although in some sections it is as low as 3m.

A carpark is located at this point just off the Fairfield-Leopold Downs Rd, and Tunnel Creek lies within the Tunnel Cave located just a few metres away.

During the dry season, this day use area is enjoyed by visitors walking through the tunnel for 750m to the other side of Napier Range, wading through pools of water using torch light in the dark cave for navigation and watching for bats and marvelling at stalactites that descend from the roof in many places. Some aboriginal painting can also be spotted just inside the cave entrance on the cave ceiling.
