Karlu Karlu, The Devils Marbles: Australia’s Sacred Landscape
The Karlu Karlu, Devils Marbles Conservation Reserve features one of Australia‘s most striking and sacred landscapes. A collection of red boulders that look as though they were carefully sculpted and intentionally positioned have been the source of endless wonder and speculation since the first humans roamed the Australian Outback over 50,000 years ago.

In 1870, explorer John Ross commented that Australian Outback was so desolate that it appeared that the devil himself had passed through and dropped his marbles. Long before anyone of European descent set foot in Australia, a handful of Aboriginal communities considered Karlu Karlu— or “round boulders,” as they called the area—to be sacred land.
Most Aboriginal stories about the origin and significance of Karlu Karlu are only shared among people who consider the landscape sacred. However, there is a widely told story about a Devil Man named Arrange who was wandering the Outback weaving a hair string belt. Arrange dropped clumps of hair as he traveled. Arrange’s discarded hair morphed into a series of red boulders.

Geologists state that the distinctive granite boulders of Karlu Karlu The Devils Marbles formed when tectonic activity and hardening magma caused rock from the Earth’s interior to rise to the surface. The temperature extremes of Australia’s Outback—heat in the day and cold at night—cause the boulders to continually change. Some boulders are even split cleanly in half as though they were cleaved by a giant’s axe.

Visitors from around the world flock to Australia‘s remote Northern Territory to see Karlu Karlu/The Devils Marbles with their own eyes. Visitors can walk among the boulders, snap photos, picnic, and camp in a sacred space which is currently co-managed by the Australian Parks and Wildlife Service and a group of dedicated Aboriginal traditional owners. Few places on Earth leave visitors with a stronger sense of wonder than Karlu Karlu/The Devil’s Marbles.

- Access
- The reserve is about 100 km south of Tennant Creek off the Stuart Highway and is listed open year-round. NT Parks requires most non-resident visitors to hold an NT Parks Visitor Pass; NT residents are exempt and may be asked for proof. Stay on marked tracks, do not climb the culturally significant boulders, carry water, and check heat and park alerts before setting out.

- No separate Karlu Karlu gate price is listed. The NT Parks Visitor Pass is required for most visitors to the Territory: 1 day A$10 adult/A$5 child; 3 days A$20/A$10; 2 weeks A$30/A$15; 1 month A$45/A$22; annual A$60/A$30. NT residents are exempt. Camping is separately booked and paid.
- Time needed
- The NT Parks fact sheet describes the easy Karlu Karlu Walk from the day-use car park as a 20-minute return walk. The 4 km Nurrku Walk is a longer option; the reserve gives no standard duration for that walk or a full visit. Allow extra time for signs, rest and the dispersed boulder groups.
- Best season
- NT Parks recommends the cooler months, April–September. It warns that October–April temperatures can exceed 40°C; check heat alerts, carry water and avoid strenuous walking in the hottest part of the day. The reserve was designated an International Dark Sky Sanctuary in August 2026, so night-sky viewing is also possible when conditions and safety permit.
