Kati Thanda-Lake Eyre National Park is located about 750km north of Adelaide.
HOW TRAVELERS FROM ADELAIDE OR DARWIN ON THE STUART HIGHWAY CAN ACCESS THE LAKE EYRE N. PARK VIA COOBER PEDY
- WILLIAM CREEK (approximately 60 kilometres east of the park) – Access Kati Thanda via the Oodnadatta Track and Halligan Bay Public Access Route.
- MARREE (95 km north-west of the park) – Access Kati Thanda via Muloorina Station and Level Post Bay Public Access Route.
You will need a four-wheel drive to access the park, but first CHECK CURRENT ROAD CONDITIONS. See map as at 20th May, 2025, below.
Top tip from Dept of Environment: Public Access Routes (also called PARs) are not part of the formal road network. They provide public access over privately owned land to key points of interest (like national parks).
It’s important to remember these PARs are unsealed dirt tracks and rain can quickly change conditions, which may mean they need to close for public safety.

Distance: Coober Pedy to Marree = 4h 43m (376 km)
Distance: Marree to William Creek = 2h 26m (204 km)
Travelers will need to plan carefully, and check fuel, food, water, and emergency supplies before heading out onto unsealed roads. Do not take risks. Volunteers at local Emergency Services also have jobs. CALL 000 for emergencies.
