San Onofre State Beach is a 3,000-acre (12 km2) state park located in San Diego County, California, USA. The beach is 3 miles (5 km) south of the city of San Clemente on Interstate 5 at Basilone Road. The state park is leased to the state of California by the United States Marine Corps. Governor Ronald Reagan established San Onofre State Beach in 1971. With over 2.5 million visitors per year, it is one of the five most-visited state parks in California, hosting swimmers, campers, kayakers, birders, fishermen, off-duty Marines, bicyclists, sunbathers, surfers, and the sacred Native American site of Panhe. It is named after the fourth-century saint Onuphrius.
