Borrego Palm Canyon Campground (Anza-Borrego Desert SP)
The designated campground inside the desert park, 88 miles out: water-and-electric on select sites, rigs to 35 feet, $35 a night on a 6-month window. It is the organized base for desert trips — with the caveat that state-park rules govern what runs where inside park boundaries, so the machine's legal terrain comes from the listing's access notes, not assumption.
