Bombay Beach is a census-designated place (CDP) in Imperial County, California, United States. It is located on the Salton Sea, 4 miles (6.4 km) west-southwest of Frink and is the lowest community in the United States, located 223 feet (68 m) below sea level. The population was 295 at the 2010 census, down from 366 in 2000. The population estimate for 2020 was 415. It is part of the El Centro, California, metropolitan statistical area.
Bombay Beach was once a popular getaway for beachgoers until the 1980s, when the draining and increasing salinity of the Salton Sea destroyed the lake's ecosystem and drove businesses and private landowners out of the area, rendering Bombay Beach a ghost town. Despite this, by 2018, a number of people had moved into the area, and the town's many abandoned structures and features from its past have drawn visitors back in. An article in The Guardian stated that it was "enjoying a rebirth of sorts with an influx of artists, intellectuals and hipsters who have turned it into a bohemian playground." The Bombay Beach Biennale, an annual art festival, is held here.
