As far as salty bodies of water located directly on a fault line go, the Salton Sea is pretty unique. The largest inland lake in California, it's positioned on the San Andreas fault at more than 200 feet (61 m) below sea level. Geothermal activity and unique landscapes such as bubbling mud and sand dunes can be seen nearby.
A popular state park and recreation area, the Salton Sea has much to offer boaters, campers, hikers, and bird watchers, and is home to more than 400 species of birds as well as some fish. Though created by accidental irrigation overflow at the turn of the 20th century, only a trickle of fresh water runs to the lake now.
Learn more about the history and geography of the distinct area on a Jeep tour of Earthquake Canyon, or visit the park by bike to make the most of Southern California's natural offerings.
The Salton Sea is located between Coachella and Imperial counties in southeastern California, 60 miles (97 km) outside of Palm Springs. It's about a three hour drive from Los Angeles, and can be accessed on Hwy 111 from Indio. There is a state park admission fee of USD 5.
The lake is accessible from most points, and its visitor center is open Friday through Sunday during the summer.
