Devils Marbles: Why You Should Camp Here
Most people driving the Stuart Highway pull over at Devils Marbles (Karlu Karlu), take a photo of the massive granite boulders, and drive on. They spend 30 minutes.
They're missing 90% of the experience.
What Are They?
Karlu Karlu ("round boulders") is a cluster of enormous granite boulders — some balanced impossibly on top of each other — scattered across a shallow valley 105km south of Tennant Creek. They range from 50cm to 6m across.
Geologically, they're the exposed remnants of a granite intrusion formed 1.7 billion years ago, shaped by millions of years of weathering.
Why They're Sacred
For the Warumungu, Kaytetye, Alyawarra, and Warlpiri peoples, Karlu Karlu are among the most significant sacred sites in Central Australia. The boulders are believed to be the eggs of the Rainbow Serpent. The site has been a meeting place for ceremonies, trade, and cultural exchange for thousands of years.
Why You Should Camp
Sunset
At sunset, the boulders transform from grey-brown to deep orange-red. The colour deepens over 30 minutes as the sun drops. Shadows stretch between the boulders creating dramatic contrasts.
Stars
Karlu Karlu has zero light pollution. On a clear night (which is almost every night), the Milky Way stretches overhead in vivid, three-dimensional detail. You can see satellites crossing the sky. The Southern Cross is so bright it doesn't look real.
Sunrise
Even better than sunset. The boulders glow orange against a pre-dawn purple sky. Mist sometimes sits in the valley. The silence is complete except for birdsong.
The Campground
- ●Cost: $6.60 per person per night
- ●Facilities: Basic toilet (no water, no showers)
- ●What to bring: All water, all food, camping gear, warm sleeping bag (desert drops to 5°C at night in winter)
- ●How to pay: Self-registration on-site
It's one of the most basic campgrounds in Australia — and that's exactly why it's special. No generators, no caravans with TVs, no light pollution. Just you, the boulders, and the sky.
Photography Tips
- ●Sunset: Walk between the boulders during golden hour. The balanced boulders make extraordinary silhouettes
- ●Stars: Bring a tripod. 15-25 second exposures at ISO 3200-6400 capture the Milky Way behind the boulders
- ●Sunrise: Set up before first light (5:30am in winter). The colour change happens fast
- ●Wide-angle lens for the boulder field, telephoto for details of individual balanced rocks
