Ocotillo Wells State Vehicular Recreation Area
Ocotillo Wells is an area in the California desert where dirt bikes, ATVs, dune buggies, and other off-road vehicles can go pretty much anywhere. There are several campgrounds where camping is free. The one I stayed at had two pit toilets, an overfull dumpster, and about a dozen sites with fire pits and picnic tables under sun shades. Besides the noise from the off-road vehicles, there were a couple of tilt-rotor airplanes that made many low passes. Internet via Verizon was slow.
