This is a large compacted dirt lot advertised as primitive camping within the park (although there are no signs located here indicating so). There are lots of other areas throughout the park to camp, but it is indicated on the map. I got confirmation from staff at the Visitor's Center as I needed someplace more accessible (I have a 2WD campervan; most other areas in the park need 4WD due to the sand.) No amenities. It's mostly a trailhead for hiking; we saw about a dozen people total Wednesday & Thursday in late February.

Basically a big parking lot. There are better primitive campgrounds if you want your own space, like Yaqui Wash down the hill. No bathrooms here.
