The Salton Sea is a odd place, and definitely worth a visit. These campgrounds place you a short walk from the water, where the shores are made of fish bones.

PROS: Inexpensive - Sites almost always available - Clean - Unique experience

CONS: A major train line is right near the campsite, so you'll hear a train going by almost every hour of the day. They don't use there horns near the camp though, so It didn't bother us at all, but light sleepers may want ear plugs.

The campground is well maintained, with decent size campsites, clean bathrooms, and even showers ($0.50) available. Each site has a shade structure, fire pit, picnic bench, and enough room for several tents. There are great day use picnic areas near the water, with shade structures, picnic benches, and grills.

This is our second time staying here and it was just as nice as the first time. The camp hosts are always friendly and helpful. They keep the campgrounds in great shape, and patrol the area often. 

There are amazing photo opportunities here, along with all the abandoned buildings in the nearby towns, Over 400 bird species have been documented at the Salton Sea, and Salvation Mountain/Slab City are only about 40 mins away.
