Karlu Karlu—also known as the Devils Marbles—is one of the Northern Territory’s most iconic natural wonders, celebrated for its colossal rounded boulders, rich Aboriginal culture, and unforgettable sunrise and sunset vistas.

Overview

Set within the vast desert plains of the Barkly Tablelands, Karlu Karlu / Devils Marbles Conservation Reserve is a landscape that feels almost otherworldly. Here, enormous granite spheres—some perfectly balanced atop one another—dot the ochre earth, glowing fiery red in the early morning and late afternoon light. These formations were shaped over millions of years through erosion and exfoliation, creating a natural sculpture garden that continues to evolve.

Beyond its geological spectacle, Karlu Karlu is a place of deep cultural significance. The Warumungu, Kaytetye, Alyawarra, and Warlpiri peoples consider this a sacred site, with Dreamtime stories describing the boulders as the eggs of ancestral beings. Visitors are asked to respect cultural protocols, including staying on marked paths and refraining from climbing the formations except at designated lookouts.

Things to Do

• Explore the Boulders on Foot
  Wander through a maze of rounded monoliths along short self‑guided walking tracks. Interpretive signs explain the geology, cultural stories, and wildlife that call the reserve home.
• Photography & Sightseeing
  Sunrise and sunset are the most spectacular times to visit, when the boulders blaze with rich reds and golds—perfect for photographers and nature lovers. Camping Under the Outback Sky
• Stay overnight at the scenic bush campground, complete with fire pits, picnic shelters, and toilets. Watching the boulders shift colours at dusk and dawn is a highlight of any Red Centre journey. Campsites must be booked online in advance.

How to Get There

Karlu Karlu lies 100 km south of Tennant Creek and roughly 400 km north of Alice Springs, directly off the Stuart Highway. The site is well signposted and easily accessible by car, making it a popular stop for road‑trippers exploring the Red Centre.

Once you arrive, the best way to explore is on foot—there are no formal long-distance trails, but several informal walking paths weave through the formations.

Best Time to Visit

The cooler months from April to September offer the most comfortable conditions for walking and sightseeing. While the reserve can be visited year‑round, summer temperatures can be extreme, so bring plenty of water and sun protection.
