Karlamilyi National Park
Park Vast remote desert national park in Western Australia
Remote Karlamilyi (Rudall River) National Park in Western Australia protects desert gorges and seasonal waterholes; visitors undertake 4WD tracks to see rugged ranges, Aboriginal heritage and sparse wildlife.
Karlamilyi National Park is a large, remote conservation reserve in central Western Australia, in the Great Sandy Desert region, known for desert river systems and rugged ranges. It is one of the largest parks in the state.
Established on land long used by Aboriginal peoples, the park covers country traditionally associated with Martu and neighbouring groups. It was formerly known under a different European name and later renamed to reflect indigenous language and place names; management recognises Aboriginal cultural values.
The park sits in central Western Australia in a sparsely populated desert area, well inland from the coast and hundreds of kilometres from the nearest major regional centres. Access is by remote unsealed roads and tracks.
- Access: Located in a very remote part of central Western Australia; travel into the park typically requires long-distance 4WD tracks and self-sufficient logistics.
- Traditional owners: Home country of local Aboriginal groups who maintain cultural connections to the land and who have guided and native title interests.
What to See #
- Rudall River: A major ephemeral watercourse running through the park that forms permanent and seasonal waterholes and gorges which support wildlife in an otherwise arid landscape.
Tips for Visiting Karlamilyi National Park #
- Visit in the cooler, dry months (roughly April-September) when temperatures are bearable and unsealed access tracks are more likely to be passable; avoid the summer wet/hot period when travel is hazardous.
- Access is remote and requires a high‑clearance 4WD - Parnngurr (formerly Cotton Creek) is the nearest community and common base for entry, so plan fuel, supplies and an overnight staging stop there.
- Check road conditions and entry requirements with Western Australia Parks/DBCA and the Parnngurr community before you go; there are no visitor facilities in the park and communication is limited, so confirm route and permissions in advance.
