Sick of the sun? Then cool down underground at Tunnel Creek, which cuts through a spur of the Napier Range for almost 1km. It was famously the hideout of Jandamarra (a Bunuba man who waged an armed guerrilla war against the police and white settlers for three years before he was killed). In the Dry, the full length is walkable by wading partly through knee-deep water; watch out for bats and bring good footwear and a strong torch.
There's rock art in the area around the far entrance. Camping not permitted.
