The Purnululu National Park is a World Heritage Site in the East Kimberley region of Western Australia.

These outstanding examples of cone karst that have eroded over a period of 20 million years are of great beauty and exceptional geological interest.The World Heritage status of the region was created and negotiated in 2003, and the adopted boundary of the existing national park.

They provide an outstanding example of land formation by dissolutional weathering of sandstone, with removal of sand grains by wind, rain and sheet wash on slopes.

The track is 53 kilometres (33 mi) long and is usable only in the dry season (about 1 April to 31 December) by four-wheel-drive vehicles.

Access by air is less demanding; helicopter flights are available from Bellburn Airstrip[9] in the national park, and from Warmun roadhouse.
