The campground is on a parking lot, next to the beach. Not much to do here but look at the sea and the mountains. I had full hookups, and camping on a parking lot at least kept the sand away from you, so no tracking inside.
The only fish remaining are tilapia, and you can fish for them and even eat them, but the water receives most of its replenishment from agriculture, so there are probably pesticides in the fish. Another strange thing is that the dead fish are sort of preserved by the salt, so they litter the beach. You can see the bodies of the dead fish in this photo.
In spite of the dead fish and the salty water, this sea is on a major flyway, so it attracts millions of birds every year. You can see some gulls here and some ducks and other birds floating on the calm water. I only walked on the beach once, and then had trouble getting off of it without the barnacles getting into my shoes and cutting into my feet!
In spite of all its problems, the Salton Sea is a beautiful and peaceful place. However, while it was in the low 70s while I was here, it can get to 120 in the summer, so I would be careful about what time of year I would choose to visit.
