For a captivating visual experience and magical encounter with nature, the 2km sealed loop through the Devils Marbles is a must. Located 106 kms south along the Stuart Highway thousands of gigantic, rounded granite boulders are scattered over a valley, and these weathered boulders balancing precariously some up to more than six metres in size owe their shape to millions of years of erosion. This Conservation Reserve has a bush camping area, interpretive displays and visitors can wander around the site along a network of informal walking tracks. They are spectacular at any time of day but are particularly striking at sunrise and sunset.

Step into a landscape of ancient granite boulders at the Northern Territory’s first Dark Sky Sanctuary.

The Warumungu people know this sacred site as Karlu Karlu - the Devils Marbles - where millions of years of weathering have carved these extraordinary granite formations.

Follow the self-guided trails to learn how the landscape came to be, then settle into the bush campground as sunset washes the boulders in colour.

Once night falls, look up. As the Territory’s first International Dark Sky Sanctuary, this is one of the best places in the outback to watch the stars.
