Bolsa Chica State Beach, State beach along Pacific Coast Highway in Orange County, US.

Bolsa Chica State Beach is a 3-mile (5 km) stretch of ocean beach in Orange County, running from Warner Avenue in Sunset Beach south to Seapoint Avenue, where Huntington City Beach begins. The city of Huntington Beach surrounds it to the north and east. The sand is dark and damp at the waterline, with small foamy waves breaking along the shore.

The 169-acre site was added to the state park system in 1960, after locals had long called it Tin Can Beach. In 1967 a nuclear power and desalination plant was planned on a man-made island offshore, meant to produce more electricity than Hoover Dam; chairman Jack K. Horton abandoned the plan in 1968 when Southern California Edison could not raise the capital.

Corky Carroll's Surf School operates by Lifeguard Tower 18, and surf fishing targets perch, corbina, croaker, cabezon, shovelnose guitarfish and sand shark. Across Pacific Coast Highway, the Bolsa Chica Ecological Reserve draws birdwatchers. Fire rings are available for beach gatherings.

Lifeguards are on duty year-round, and there are restrooms with showers along the beach. Parking is paid and can fill quickly on weekends.

The beach was nicknamed "Tin Can Beach" before its 169 acres joined the state park system in 1960. In 1967 a nuclear power and desalination plant was planned for a man-made island offshore, meant to outproduce Hoover Dam; chairman Jack K. Horton abandoned the plan in 1968 when Southern California Edison could not raise the capital.
