Salton Sea and Vicinity Campgrounds is located near Calipatria, CA. The trail is primarily used for camping and is accessible from April until October.
This large salt lake in the deserts of southern California is famous for being BELOW SEA LEVEL, which is what interested my parents and I as we drove the fast highway from Palm Springs to see Mexicali, Mexico, just across the border from Calexico, CA. The wide , sparsely vegetated valley is very flat, so there are not many impressive views approaching the lake, except for having a shimmering, mirage like quality, being also quite warm---probably lower 90's in mid September. We turned off onto one of several side roads that led through a tiny cluster of dusty mobile homes, and then to the shore. Saw no people around, only a few dry docked vessels. The water was warm, very shallow, and of course, salty! The lonely setting and open space was interestingly surreal.
