Tunnel Creek National Park is one of the Kimberly region’s most famous attractions. Though small in size compared to the other national parks that cover the Kimberly region, at just 91 hectares, Tunnel Creek has a huge attraction – being home to Australia’s oldest cave system.
Tunnel Creek is located in the Napier Range, the same range as the nearby Geikie Gorge. The remains of an ancient reef system formed 350 million years ago, the limestone that forms Tunnel Creek is what makes this region so ancient. The tunnel of tunnel creek runs for 750 meters. It reaches a maximum height of 12 meters, and a maximum width of 15 meters. There are a number of animals making their home in the caverns, including at least five species of bat, which led to the cave’s nickname of The Cave of Bats. Freshwater crocodiles occasionally take up residence in the large pools of water that dot the floor of the cave.
Tunnel Creek became famous in the late 1800s as the hideout of the Aboriginal outlaw and leader Jandamarra. The cave has been used by the Aboriginal people for hundreds of years, and the walls are covered in their artworks.
Tunnel Creek is accessible only by 4WD, though a day tour to the park is recommended. Facilities at the park include toilets, picnic tables and an information shelter only. Visitors are recommended to come prepared with a torch, sneakers and jumper. Visitors should not enter the cave during rainfall or whilst rainfall is imminent, as the cave is subject to flooding.
