Wonderful dispersed free camping in Mojave National Preserve. Find the first road adjacent to the white cross memorial. We arrived after sunset and we reluctant to drive too far down the uneven and non-maintained dirt road, but were rewarded with an outstanding campsite for our risky persistence!
The road has many wash out holes and soft sand, but I was able to navigate successfully (and slowly) in an AWD Honda Element. Higher clearance four-wheel drive vehicles will be able to explore additional camp sites further down the road, but there are a handful of sites near the entrance.
Tip: Stargazing at this site was outstanding. Rock formations provide comfortable platforms for laying on your back and watching for shooting stars. Camped here in December with overnight lows around 30 degrees. Bundle up and enjoy!!
