Devils Marbles located near Wauchope, approximately 114&100bsp;km south of Tennant Creek, in the Northern Territory. The site is known as Karlu Karlu to the land's Aboriginal traditional owners. The ‘Devils Marbles’ or ‘Karlu Karlu’ with its gigantic, rounded granite boulders, some spectacularly poised, is a remarkable landscape. Scattered clusters of these ‘marbles’, including many balancing rocks, are spread across a wide, shallow valley. The Devils Marbles is a nationally and internationally recognised symbol of Australia’s outback.
