Anza-Borrego Desert State Park, the largest state park in California, features several hundred miles of dirt roads, a dozen wilderness areas and numerous hiking trails, plus “an unparalleled opportunity to experience the wonders of the California Desert.” There is both boondock camping for free and developed campgrounds for fees on this magnificent and vast start park.

Other dry camping opportunities on Bureau of Land Management lands are numerous in the surrounding region.
On one trip we found a public lands area just east of Peg Leg Monument Road off San Diego County Road S-22. There were no signs, we just spotted a couple dozen RVs camped a few hundred yards off the paved highway. We traveled down a fairly well-graded dirt road and drove for about half-a-mile, then pulled over.
We talked with one couple from Nevada who have been coming to that same area for four years in their class B Rialto. They had been there a week and usually stay about a month.
Absolutely incredible, stark landscapes.
