Interesting place
Stayed one night at site overlooking the Salton Sean. Quite lovely. However, if you walk down to the water's edge, you'll see fish carcasses due to the increasing salinity of the water (and other issues.) There was a nice breeze and there was no smell that others have talked about. There is a rail line nearby but the noise didn't bother us during the night. No specific camping sites but there were picnic tables and most sites seem pretty level.
There are 2 showers and some toilets. They appeared to be fairly decent. Most campers at the campground were in self-contained units so the facilities seemed to be lightly used.
