If you’re doing the long drive from the Bay Area to LA, a nice place to stay is Mercey Hot Springs.  It takes about 20 minutes to get there from the freeway and is in the middle of nowhere.  Camping is $50 per person, but it gives you access to the pool and the hot tubs.  There are both clothing optional hot tubs and hot tubs for bathing suits.  The best campsites are the ones with no hook-ups.  They are under the trees and right next to the pool.  The RV sites with hook-ups are in an open field area with no tree cover.  There are also airstreams and cabins available to rent.  Camping gives you 24 hour access to the hot tubs.  There is no food available here and the closest town is 30 minutes away so be sure to come prepared.  There is also a sauna and a nice hike up in the hills.  Nice quiet place. Everyone is super chill and no one really bothers you about swimming after hours.
