Karlu Karlu / Devils Marbles: A campervan guide to the NT’s balancing boulders

Right beside the Stuart Highway in the Northern Territory’s Barkly region, colossal rust-red spheres are gathered in clusters that look almost impossible, some split clean in half and others teetering in perfect balance. Known to Aboriginal Traditional Owners as Karlu Karlu, meaning round boulders, this sacred landscape has been shaped over millions of years and glows brilliantly at sunrise and sunset.

It’s an easy and rewarding stop on a Red Centre road trip, especially when you have the freedom of a campervan to linger for golden hour, camp under the stars, and wake for first light without rushing the drive.

Why do people go to Karlu Karlu / Devils Marbles Conservation Reserve?

Karlu Karlu / Devils Marbles is one of the iconic outback landscapes on the Stuart Highway: giant, rounded granite boulders scattered and stacked across the plain, glowing deep red at sunrise and sunset. Travellers come for the instant outback impact. The boulders seem to have dropped from the sky, scattered across more than a thousand hectares in photogenic stacks and rounded domes. Geologically, the marbles are exposed granite that has cracked, weathered and rounded over vast time. No two visits feel the same as surfaces continue to flake, split and transform with the elements.

The reserve is culturally significant to Traditional Owners (Kaytetye, Warumungu, Warlpiri and Alyawarra peoples), who ask visitors not to climb the boulders. There are short walks you can do among the rocks, and simple bush camping close to the formations if you want to stay the night.

How long should I spend at Karlu Karlu / Devils Marbles Conservation Reserve?

A short stop (45–90 minutes) covers a stroll through the nearest clusters and a few viewpoints. For the full magic, stay overnight. Camping on site lets you capture both sunset and sunrise when the rocks truly glow, and it opens time for unhurried walks among the boulders. One night is usually enough to catch both light shows.

The reserve also works perfectly as a day trip from Tennant Creek, with relaxed time to explore and return before dark.

How to get to Karlu Karlu / Devils Marbles Conservation Reserve

Karlu Karlu sits right on the Stuart Highway, around 95 to 100 kilometres south of Tennant Creek. It is about a 4.5-hour drive north of Alice Springs and forms a natural pause for anyone tackling a north-south road journey.

The reserve is well signposted and visible from the road, with a short access road leading directly to the day-use area and campground. The drive is on sealed highway and suitable for all vehicles, including large campervans and caravans.

Best time to visit Karlu Karlu / Devils Marbles Conservation Reserve

The reserve is open year-round, but the most comfortable visiting window is during the cooler months from April to September. The summer months can get quite hot, with temperatures exceeding 40°C.

If you prefer quieter walks, consider shoulder-season dates on either side of winter, or time your visit for early morning and late afternoon when day-trippers are yet to arrive or already heading off.

Weather in Karlu Karlu / Devils Marbles Conservation Reserve

This is arid country. Expect hot, dry conditions for much of the year. Summer may include storm activity and bursts of rain, particularly between December and March, which can change road conditions quickly in surrounding areas. Winter offers sunny days and cool to cold nights. Pack layers for evening and dawn, including a warm jacket if you plan to be out early or late for photography. No matter the season, sun protection is essential.

Carry more drinking water than you think you will need, wear a wide-brimmed hat and lightweight long sleeves, and take breaks in the shade during the middle part of the day. Starting your walks at first light or late afternoon maximises comfort and gives you the best light on the rocks.

Entry fees and permits for Karlu Karlu / Devils Marbles Conservation Reserve

Things to see and do at Karlu Karlu / Devils Marbles Conservation Reserve

Once parked, the best way to discover Karlu Karlu is on foot. There are no formal long-distance trails here, just simple, informal paths and sandy corridors weaving between the boulder fields.

The Nyanjiki Lookout provides a wide perspective across the reserve and is a beautiful spot to appreciate the scale of the place. Sunrise and sunset are the headline acts. Bring a tripod if you enjoy photography, or simply sit back on a slab of granite and watch the light show unfold.

After dark, the outback sky is brilliant. If conditions are clear, step away from camp lights for a few minutes of stargazing and the possibility of astrophotography. Wildlife watching is also woven into every stroll.

Remember that the marbles are a sacred site. Please do not climb on the boulders. Keeping to the ground-level paths protects both the rocks and the cultural values of the reserve.
