LinksHere are some general BLM camping regulations (in this case for the Mojave Desert near Barstow) as published on an official website:
Except for "special areas" with specific camping regulations, visitors are welcome to camp anywhere on BLM managed land.Note that it costs $6 to camp in a campground but nothing just outside it. And here are some exact local regulations, as published in the Federal Register. Although the exact regulations vary from place to place, the 14-day limit seems pretty universal. The only thing that varies is how far away you have to go when the 14 days are over and how long you have to wait before returning. Again, if you keep a low profile and never develop what appears to be a permanent encampment, the 14-day limit is pretty meaningless.
