Turn off Hwy 10 onto 168 (it is paved) and head north. There will be several roads you can either turn left, or right onto. They go for miles, so don't worry if there are people camped at the turn offs. We stayed 3 nights and 4 days. The roads and sites (at least where we drove and camped) are not power sand. Nope, more like small gravel. There were a lot of 5-wheels in there and we didn't sink in at all. Good spot, we would stay there again. There are fire pits. Quick drive up to Joshua Tree canyon from some exploring.
