Saline Valley is a destination. The hot tubs are a well kept secret. The tubs have been constructed over the years by volunteers. Well maintained by NP staff and visitors, daily. Great Desert views, no privacy, but at least three distinct camping areas.
WARNING: This is a clothing optional AREA, within the NP. The few locals are friendly, but stuck in the sixties. Psychedelic painted school bus is not unusual during the Xmas season. Xmas is a VERY big time there, with folks coming from several countries.
DO NOT get into the hot tubs with sand on your feet. Rinse in the runoff. Sand is a PITA to remove from the tubs.
There are NO services, although I heard the camp host had a satellite phone, and a generator to run a welder for repairs. Nearest store is probably 50 miles away.
Info from about 2000, one and only time I was there. Ready to go back.
