I had planned to stay in the park when I visited early February 2021. All camping was still closed when I got there, so I found this dispersed camping site just outside of the park. It was easy to find, even though it was already dark. There were several other campers already out there, but there's enough space where it still felt somewhat private.
Basically this is an abandoned housing development, so it's super flat and easy to find and unoccupied space. Basically it's the pad where a house was going to be built.
There are no amenities, no water no bathroom no nothing. But it is so quiet! I stayed up late and when everyone went to bed it was the quietest I've ever heard. No road noise, no planes overhead, absolutely nothing. You don't realize what real silence sounds like until you experience it!
Definitely would recommend, cheap (free!), Easily accessible in any vehicle, great view of the desert and night sky!
