Karlu Karlu / Devils Marbles Conservation Reserve protects 1,802 hectares of granite country on both sides of the Stuart Highway, 100 km south of Tennant Creek. The karlu — round boulders, in the name shared by the Warumungu, Kaytetye, Alyawarr and Warlpiri peoples whose country this is — formed when molten rock cooled beneath a sandstone layer and fractured into blocks, then weathered into rounded masses balanced one on another, some standing up to six metres. Ownership was handed back to Traditional Owners at the site on 27 October 2008, and the reserve is now jointly managed with Parks and Wildlife rangers.
Almost the entire reserve is a registered sacred site, and the Traditional Owners ask that visitors do not climb on the boulders. You see it from flat, signposted loops — a 20-minute return walk from the day-use car park, a 4 km loop through the wider rock country and a lookout over the whole valley. The boulders go deep red in morning and evening light, and in August 2026 the reserve became Australia's third International Dark Sky Sanctuary.
Go if…
- You're driving the Stuart Highway between Alice Springs and Tennant Creek and want one stop that explains the country either side of the road
- You photograph granite at golden hour — the boulders are at their reddest in the first and last light of the day
- You want a genuinely dark night sky without leaving the highway: the reserve has no permanent lighting
- You're travelling with a caravan or motorhome and want a quiet bush camp with fire pits and short walks at the door
Skip it if…
- You want shade, water or swimming — there is no swimming here and no water provided in the reserve
- You're travelling October to April and plan to walk in the middle of the day, when temperatures can exceed 40°C
- You want to climb and scramble over rocks: this is a registered sacred site and climbing the boulders is not permitted
- You expect phone coverage, shops or fuel inside the reserve — the nearest fuel is 9 km south at Wauchope
What to expect
Reviewed
You turn off the Stuart Highway at a signed entrance and the boulders are already there, heaped across both sides of the road. The day-use car park at the northern end has a shelter, information signs and toilets, and the Karlu Karlu Walk starts beside it: a flat, signposted loop the parks factsheet describes as a 20-minute return walk from the car park, with panels explaining how the karlu formed when molten rock cooled under a sandstone layer, fractured into rectangular blocks and was rounded by water working the cracks. What you walk between is the result — rounded masses, many balanced one on another, some split along old fractures into halves that lean apart. Caravans and motorhomes fit the day-use area and the signed campground turnoff, and the whole reserve is 2WD country on sealed road. The Traditional Owners ask that you do not climb on the boulders, and the tracks are laid out to keep you on the ground while threading between the heaps.
From the campground at the southern end, three Grade 2 loops fan out. The Mayijangu Walk is the shortest at 800m, with a short detour to Nyanjiki Lookout; the Yakkula Walk runs about 1.5km — around 30 minutes — east into the marble group; and the Nurrku Walk makes a 4 km loop through the formations to the north, passing the lookout on the way back to camp. All three are flat, clearly signposted and need no experience, and they are the way to see the reserve without walking on anything that matters. The signs ask you to stay on designated roads and tracks, because historic and cultural items, plants and wildlife are all protected here, and the karlu themselves are part of a registered sacred site rather than a climbing frame.
Nyanjiki Lookout is where the reserve reads as one place: a panorama over the whole valley, boulder heaps scattered across a wide, shallow basin with the Barkly plain running to the horizon. The rocks are granite, and many stand up to six metres tall, stacked and cracked with spinifex and dry scrub at their feet. The heaps make their own sheltered micro-environments — the native rock fig (Ficus brachypoda) grows in the crevices — and the wildlife is small and busy. Black-headed goannas work the boulder cracks while the larger sand goannas hunt the spinifex clumps between them, fairy martins attach bottle-shaped mud nests to the undersides of overhangs, and zebra finches and painted finches flock around the rocks. More than 80 bird species, 116 plant species, 10 mammal species and 30 reptile species are recorded across the 1,802 hectares, and you will see a fraction of them from the track, which is normal for this country.
Stay into the evening and the place changes register. The boulders go deep red in the last light, the day-use crowd clears, and the campground at the southern end settles in — 24 unpowered caravan and trailer sites plus a tent area, pit toilets, sheltered picnic tables and fire pits with barbecue plates. There is no water and no firewood here, so both need to be in the vehicle before you arrive, and generators and drones are not permitted. In August 2026 the reserve was recognised as an International Dark Sky Sanctuary, the third in Australia and the first in the NT, with no permanent lighting anywhere in the reserve and a commitment to keep it that way; Parks and Wildlife staff run campfire talks on night-sky viewing through the winter months. Fires go only in the designated fire pits, pets are allowed in the day-use car park on a lead but not in the campground, and the nearest fuel and stores are at Wauchope, 9 km south.
Where to stay
Most people camp in the reserve itself and treat it as a one-night stop on the Stuart Highway; the nearest beds, fuel and meals are at Wauchope, 9 km south, and full town services are at Tennant Creek, 100 km north.

What to do here
8 walks & sights
Karlu Karlu Walk
The reserve's introduction and the first thing most people walk: a flat, signposted loop from the day-use car park past heaps of balanced granite. Interpretive signs explain how the karlu formed — molten rock cooling beneath sandstone, fracturing into blocks and being rounded along the cracks. The Traditional Owners ask that you do not climb on the boulders.
Nyanjiki Lookout
A panoramic vantage over the whole reserve, with the boulder heaps spread across the shallow valley and the Barkly plain running out to the horizon. It is the quickest way to understand how much country the 1,802 hectares cover, and the natural place to be at sunrise or sunset. It also sits on the return leg of the Nurrku Walk.
Mayijangu Walk
The shortest of the three campground loops, with a short detour to Nyanjiki Lookout. It is flat, clearly signposted and suited to families and anyone short on time or travelling in the heat of the day. Combine it with the Yakkula Walk for a longer circuit.
Yakkula Walk
A loop east into the marble group, starting from the southern end of the campground and passing a toilet on the way. The track is flat with no steps and clearly signposted, and it puts you closest to the stacked and split boulders without climbing anything. Third-party trackers log it at 1.5 to 1.6km, so allow a little more than the half hour most people take.
Nurrku Walk
The longest walk in the reserve, looping through the rock formations to the north and returning past Nyanjiki Lookout to the campground. It is flat and signposted but carries no shade worth relying on, so start early in the warmer months and carry water. Allow extra time for the wildlife working the boulder crevices and overhangs.
Sunrise and sunset on the boulders
The granite goes deep red in morning and evening light, and the reserve is internationally recognised for exactly this. The boulders sit on both sides of the highway, so you can work the day-use side at one end of the day and the campground loops at the other. Stay on the tracks and off the rocks — the request from Traditional Owners applies to photographers too.
Wildlife watching in the boulder heaps
The rocks are a cooler, sheltered environment for plants and animals, and small residents keep busy in them. Black-headed goannas work the crevices while sand goannas hunt the spinifex between boulders, fairy martins build bottle-shaped mud nests under overhangs, and zebra and painted finches flock around the rocks. More than 80 bird species and 30 reptile species are recorded across the reserve.
Night sky from the campground
In August 2026 Karlu Karlu was recognised as an International Dark Sky Sanctuary — the third in Australia and the first in the NT. There is no permanent lighting in the reserve and future development is bound by strict lighting rules, so the sky is the show once the highway quiets. Parks and Wildlife staff run campfire talks on night-sky viewing through the winter months.
Karlu Karlu / Devils Marbles itineraries: 1, 2 or 3 days
3 plans
One day: the marbles, the lookout and sunset
- Morning. Drive the 100 km south from Tennant Creek on the sealed Stuart Highway — about an hour — and park at the day-use area. Walk the Karlu Karlu Walk, a 20-minute return from the car park, with signs explaining how the karlu formed.
- Midday. Take the Mayijangu Walk (800m) with its short detour to Nyanjiki Lookout, then the Yakkula Walk (about 1.5km, roughly 30 minutes) east into the marble group. Stay on the tracks and off the rocks.
- Afternoon and sunset. Leave the evening light to the photographers — the boulders go deep red — then drive back to Tennant Creek, or book a site at the Karlu Karlu campground and stay on.
No nights if you drive back to Tennant Creek. The walking is the 20-minute-return Karlu Karlu Walk, the 800m Mayijangu Walk and the 1.5km Yakkula Walk. The NT Parks Pass is $10 adult, $5 child and $25 family per day, bought online before you travel, and no water is provided in the reserve — fill up at Tennant Creek or at Wauchope, 9 km south.
Two days: the full loop and a night under the dark sky
- Day 1. The 20-minute-return Karlu Karlu Walk, the 800m Mayijangu Walk and Nyanjiki Lookout, then the 1.5km Yakkula Walk before the evening light. Camp at the Karlu Karlu campground at the southern end of the reserve.
- Day 2, morning. Walk the 4km Nurrku Walk loop through the formations to the north, returning past Nyanjiki Lookout. Start early if you are travelling in the warmer months.
- Day 2, afternoon. Watch the crevices for black-headed goannas and the overhangs for fairy martins' mud nests, then drive the 100 km north to Tennant Creek for fuel, supplies and the night.
One night at the Karlu Karlu campground: the short loops on Day 1 and the 4km Nurrku Walk on Day 2. Camping is Category B at $10 adult, $5 child and $25 family, booked and paid online through the Parks Booking System before you arrive — you cannot pay at the reserve. Bring all your water and firewood, and check the Tennant Creek and Barkly park-status page before you set out.
Three days: granite, dark skies and the Barkly's gold-rush town
- Day 1. Drive in from Tennant Creek (100 km, about an hour), walk the Karlu Karlu Walk, Mayijangu Walk and Nyanjiki Lookout, then the Yakkula Walk, and camp at the Karlu Karlu campground.
- Day 2, morning. Walk the 4km Nurrku Walk through the formations to the north and back past the lookout.
- Day 2, afternoon. Slow down for the wildlife in the boulder heaps, then settle in for sunset and the night sky — the reserve carries no permanent lighting.
- Day 3, morning. One more walk in the early light, then drive the 100 km north to Tennant Creek for the Battery Hill Mining Centre, the Nyinkka Nyunyu Art and Culture Centre, fuel and supplies.
Two nights at the Karlu Karlu campground, with the 4km Nurrku Walk on Day 2 and dark skies both nights — Karlu Karlu became Australia's third International Dark Sky Sanctuary in August 2026. Camping is $10 adult, $5 child and $25 family and the NT Parks Pass is $10 adult, $5 child and $25 family per day, both booked online. Day 3 ends in Tennant Creek, 100 km north, with fuel, supermarkets and medical care.
Suggested gear for Karlu Karlu / Devils Marbles
18 items
- Water bottles or a hydration bladder Carry at least 2 litres per person on the walks.
- Water treatment tablets or a filter Treat creek and camping-area water before drinking.
- Sun hat, sunscreen (SPF 50+) and sunglasses
- Sturdy, broken-in walking shoes or boots
- Day pack (20–30 L)
- First aid kit, including blister care
- Insect repellent
- Head torch with spare batteries
- Lightweight rain jacket
- Personal locator beacon Mobile coverage is unreliable in remote parks.
- Twenty litres or more of drinking water per vehicle The reserve's own factsheet states no water is provided at Karlu Karlu, and the nearest supplies are 9 km south at Wauchope or 100 km north at Tennant Creek.
- Firewood and a gas stove No firewood is provided, fires are permitted only in the designated fire pits, and generators are banned — so a stove covers the nights the pits are full or lit.
- Warm fleece and a winter-weight sleeping bag June and July average around 24.7 to 24.8°C by day at Tennant Creek Airport and the desert cools fast after dark, so campers feel the cold even in the best season.
- A fly net and loose long sleeves Flies are at their worst through the hot months, and the exposed loops offer no escape from them or the sun.
- Offline maps and the free park map downloaded before Wauchope Phone coverage is patchy from Wauchope onward and NT Parks advises downloading maps while you still have signal.
- Full-size spare tyre, plugs and a compressor The Stuart Highway runs at 130 km/h and tyre services are hundreds of kilometres apart along the Barkly.
- A jerry can of fuel Hundreds of kilometres can separate petrol stops on this highway — fill at Tennant Creek or Wauchope and don't assume anything further along.
- Tripod and a red-light torch The reserve has no permanent lighting and is now a Dark Sky Sanctuary, so night-sky photography is worth planning for — red light keeps everyone's night vision.
How this compares
Karlu Karlu / Devils Marbles vs Tjoritja / West MacDonnell National Park
Tjoritja / West MacDonnell is the Red Centre's gorge-and-swimming leg west of Alice Springs, with cold permanent waterholes and the long-distance Larapinta Trail on the ranges above. It asks for days of walking where Karlu Karlu asks for an hour and gives back granite, red light and dark skies. Choose Tjoritja for gorge swims and trail sections; choose Karlu Karlu for a compact sacred-site stop with a night among the boulders.

Karlu Karlu / Devils Marbles vs Elsey National Park (Mataranka)
Elsey National Park at Mataranka is the Top End's thermal-spring stop — warm water, paperbark forest and the Roper River on the sealed highway north of Katherine. It is green, humid country, the opposite of the Barkly's dry granite plain. Choose Elsey for warm springs and river country; choose Karlu Karlu for balanced boulders and cool-season dark skies.

Karlu Karlu / Devils Marbles vs Nitmiluk National Park (Katherine Gorge)
Nitmiluk National Park is a gorge system you paddle and walk rather than drive past, with cruises and canoe trips above the escarpment out of Katherine. It needs a full day or more; Karlu Karlu fits into a Stuart Highway transit day. Choose Nitmiluk for gorge paddling and escarpment walks; choose Karlu Karlu for an easy-access granite stop between Alice Springs and Tennant Creek.

Before you go
- Buy your NT Parks Pass online before you travel — $10 adult, $5 child (5–17) and $25 family per day, $30 / $15 / $75 for two weeks or $60 / $30 / $150 for an open pass valid 12 months. NT residents are exempt but may be asked for proof of residency
- Book the campground online through the Parks Booking System before you arrive: camping is Category B at $10 adult, $5 child and $25 family, and you cannot pay at the reserve
- Carry all your water and firewood — the reserve's factsheet states neither is provided, and fires are allowed only in the designated fire pits
- Fuel at Tennant Creek (100 km north) or Wauchope (9 km south) and treat those as the sure stops; hundreds of kilometres separate petrol stops along this highway, and the speed limit is 130 km/h unless signposted
- Check the NT Road Report and the Tennant Creek and Barkly park-status page before each day's driving — access can change at short notice after rain, flooding or fire, and never drive through floodwater
- Take the heat seriously from October to April: temperatures can exceed 40°C, so walk the loops early or late, carry plenty of water, and watch for Bureau of Meteorology heatwave warnings
- Do not climb on the karlu — almost the entire reserve is a registered sacred site and the Traditional Owners ask that visitors stay off the boulders. Keep to designated roads and tracks and leave cultural items, plants and wildlife where they are
- No generators and no drones in the reserve; pets are allowed in the day-use car park on a lead only and are not permitted in the campground
When to go
seasons & the hard months
Come between April and September. NT Parks names the cooler months as the best time to visit, and Tennant Creek Airport averages about 24.7 to 24.8°C in June and July — warm days, dry air and cool nights that suit both walking and camping. The campground host is on site through the peak season from May to September, which is also when the reserve is busiest, so book online before you arrive rather than counting on a free site. Winter is the natural season for the night sky too, with staff campfire talks on stargazing running through the cool months at a reserve that carries no permanent lighting.
October to April is the hard season. The NT Government's heat warning runs across those months — temperatures can exceed 40°C, and Tennant Creek Airport averages 37.3°C in December and 36.8°C in January — so the short loops are best walked in the first or last hour of daylight and the middle of the day is for the car. The other factor is water falling out of the sky: storms between December and March can flood roads and close access at short notice even though rain is infrequent overall, and the surrounding Barkly roads may be unsealed or wet-affected. If you must travel then, carry more water than you think you need, check warnings before leaving, and treat any closure as final.
Questions

Yes, unless you live in the Northern Territory. The NT Parks Pass is $10 adult, $5 child (5–17) and $25 family per day, $30 / $15 / $75 for two weeks or $60 / $30 / $150 for an open pass valid 12 months, and it is bought online before you travel. It covers entry to the reserve but not camping, which is priced separately, and NT residents are exempt but may be asked for proof of residency.
The reserve straddles the Stuart Highway about 393 km north of Alice Springs — a 4 to 4.5 hour drive — and 100 km south of Tennant Creek, roughly an hour. Wauchope, the nearest settlement with fuel and limited supplies, is 9 km south of the reserve.
No. Almost the entire reserve is a registered sacred site, and the Traditional Owners ask that visitors do not climb on the karlu. Stay on the designated roads and tracks and photograph the boulders from ground level — the loops are built to get you close without walking on them.
At the Karlu Karlu campground at the southern end of the reserve — 24 unpowered caravan and trailer sites plus a tent area, pit toilets, sheltered picnic tables and fire pits with barbecue plates. It is Category B at $10 adult, $5 child and $25 family, booked and paid online through the Parks Booking System before you arrive, because you cannot pay at the reserve. Caravans and motorhomes are allowed in the main campground but not the overflow area, and generators are not permitted.
No water and no firewood are provided in the reserve, so bring both. Fuel and limited supplies are at Wauchope, 9 km south, and full supermarkets, mechanics and medical care are at Tennant Creek, 100 km north. Phone coverage is patchy from Wauchope onward, so download maps and any booking confirmations while you still have signal.
In August 2026 Karlu Karlu was recognised as an International Dark Sky Sanctuary — the third in Australia and the first in the Northern Territory. The reserve has no permanent lighting and future development is bound by strict lighting rules, which is why the stars are so good from the campground. Parks and Wildlife staff run campfire talks on night-sky viewing through the winter months.
