Munga-Thirri–Simpson Desert National Park
Go only if you have a 4WD, a satellite messenger and outback experience: enter April–November, pay the SA parks fee per vehicle, and plan two nights on the French Line or Rig Road; the park is closed 1 Dec–15 Mar and there are no walking tracks.

Rules in force · 7
- Oceania ↗Oceania's island states guard their farms and reefs at the border: tick 'yes' on the arrival card for any food, plant, animal product, soil or used outdoor gear, and let the officer decide.
- Oceania ↗Across the tropical South Pacific, cyclones are possible from November to April: choose insurance that covers weather delays and keep one spare night before a long-haul departure.
- Australia and New Zealand ↗Both countries drive on the left, with long distances between fuel stops in the outback and on New Zealand's back roads; fatigue causes more visitor crashes than speed.
- Australia ↗Almost every visitor needs a visa or an electronic authorisation (ETA or eVisitor, depending on passport) before boarding: apply only through the official Department of Home Affairs site or the official AustralianETA app, and check the rules for your passport.
- Australia ↗Declare all food, plant material, seeds, wood and animal products on your arrival declaration; undeclared items can bring on-the-spot fines or visa cancellation. When unsure, declare it.
- Australia ↗Drive on the left. An overseas licence in English (or with an official translation or International Driving Permit) is accepted for visitors; check the state rules and your rental contract.
- Australia ↗Swim between the red and yellow flags on patrolled beaches; rip currents cause most beach drownings.

Munga-Thirri–Simpson Desert National Park is the biggest national park in Australia and one of the largest in the world: about 36,000 km² of parallel red dunes, spinifex, Acacia woodland and salt lakes, declared in November 2021 by merging the old Simpson Desert Conservation Park with the surrounding regional reserve. It is a driving park, not a walking one — there are no walking tracks and bushwalking is strongly discouraged — and every route in is unsealed sand or clay reached from Oodnadatta, Birdsville or Dalhousie Springs. The park closes from 1 December to 15 March each year, when daytime temperatures can pass 50°C, and there is no mobile coverage anywhere inside it, so a satellite phone or PLB, a convoy of at least two 4WDs and a self-registered SA parks entry are the price of admission. Across the border, Queensland's Munga-Thirri National Park is a separate park.

Why go
- Australia's largest national park: parallel red dunes running for hundreds of kilometres, and you can camp beside them with no one else in sight.
- Poeppel Corner, where South Australia, Queensland and the Northern Territory meet — a 4WD milestone on the French Line.
- Approdinna Attora Knolls, rare gypsum outcrops on the Knolls Track, protected from vehicles and worth the detour.
- Desert wildlife you will not see from a highway: dune-dwelling reptiles, spinifex birds and, after rain, mass flowering.

Park rules
- Seasonal closure
- The park is closed from 1 December to 15 March every year because of extreme heat.
- Stay on tracks
- Driving off marked vehicle tracks is not allowed; fines apply, especially around the gypsum knolls.
- Bushwalking
- There are no walking tracks and walking is strongly discouraged; this is a 4WD park.
- Camping
- Allowed within 100 m of a public access track only; no toilets, water or bins — carry everything out.
- Fires
- Check total fire bans before lighting anything; wood is scarce and collecting it damages the desert.

Time out
Finding the local time zone…
Times are local to the spot (zone loading). The half-hour margin is our rule of thumb, not an official figure; light fades earlier in forest or under cloud. Carry a headlamp on any route that could run late.
Accessibility
- This is a 4WD-only park with no formed walking tracks, so it is not suitable for limited mobility or standard vehicles.
- The nearest sealed-road services and medical help are at Oodnadatta, Marree or Birdsville, hours away.
Visiting lightly
- Drive only on marked tracks; dune vegetation takes decades to recover from a single set of wheel ruts.
- Carry out all rubbish and do not bury it — the desert does not break down waste.
- Use a portable toilet or dig catholes well away from tracks, camps and salt lakes.
- Do not collect wood, plants, rocks or artefacts; everything in the park is protected.
Questions people ask
How much does it cost to enter Munga-Thirri–Simpson Desert National Park?
Entry is charged per vehicle per day by SA parks — budget roughly A$11–16 a day in 2026 (check current rates). A Desert Parks Pass of about A$150–200 covers this park and other desert parks for a year, and bush camping inside the park is free. Fuel at Oodnadatta or Birdsville is the real cost of the trip.
What are the best hikes in Munga-Thirri–Simpson Desert National Park?
There are no walking tracks and bushwalking is strongly discouraged. The park is driven, not hiked: the French Line and Rig Road are the two classic 4WD routes, with short stops at Poeppel Corner, Approdinna Attora Knolls and Lone Gum. Stay on the marked vehicle tracks.
When is the best time to visit Munga-Thirri–Simpson Desert National Park?
April to August is the sweet spot: the park reopens on 16 March, days sit in the 20s–30s°C and tracks are usually dry. September and October are still workable but hotter. The park is closed from 1 December to 15 March, when temperatures can pass 50°C.
Do I need a 4WD to visit?
Yes. Every route in is unsealed sand, clay or gibber, and 2WD vehicles cannot cross the dunes. Go in a convoy of at least two well-equipped 4WDs with recovery gear, spare fuel, water and two spare tyres.
Is there mobile phone coverage in the park?
No. There is no mobile coverage anywhere in the park, so carry a satellite phone or a PLB/satellite messenger and leave your route and expected exit date with someone.
Can I camp in the park?
Yes, but there are no designated campgrounds and no facilities. Camping is allowed within 100 m of a public access track; many people camp near the salt lakes. Bring all your water, a toilet solution and take every bit of rubbish out.
Is this the same park as Munga-Thirri National Park in Queensland?
No. Munga-Thirri National Park is a separate park across the border in Queensland. This page covers the South Australian park, which was declared in November 2021 and is the larger of the two.
