The main camping area at Lake Gairdner National Park is Waltumba, situated among Western Myall trees on the edge of the vast salt lake in outback South Australia.

The campground offers sweeping views across the lake toward the Gawler Ranges, and a moderate walking trail leads from the site up a hill for an elevated panorama.

Waltumba is an unallocated, open-style campground where visitors choose their own spot on reasonably flat ground, with ample space for larger vehicles. There are no fixed fire pits. Access requires a high-clearance vehicle, and a 4WD is recommended.

Wildlife including emus and kangaroos are commonly seen on surrounding tracks, particularly at dawn and dusk. The cooler months of April to October are the most suitable time to visit, given the region's extreme summer heat.
