Free camping is not allowed within Karijini National Park, as camping is only permitted in designated areas. The main campground in Karijini is the Dales Campground, which is managed by the Western Australia Department of Parks and Wildlife. There is a fee for camping at this site, and it operates on a first-come, first-served basis.
Outside of the national park, you may find free camping options on nearby public lands or rest areas, but it's essential to follow local regulations and guidelines when choosing a place to camp.
