Leo Carrillo State Park, State park in Los Angeles County, California, United States

Leo Carrillo State Park is a coastal park with over a mile of beach, sea caves and tide pools at the foot of the Santa Monica Mountains in southern California. The area covers more than a thousand hectares and offers both rocky sections and open sandy stretches.

California authorities opened this park in 1953 and named it after a film and television actor who supported conservation projects. A large fire in 2018 heavily damaged the area, which led to the camping facilities remaining closed for months.

The park is named after Leo Carrillo (1880–1961), a Los Angeles-born actor and conservationist who sat on the State Parks commission. Filming has long been part of the site: the cover photo of The Turtles' album Turtle Soup was shot here in 1969, and Tom Petty's "Mary Jane's Last Dance" video ends in one of the sea caves.

The park offers areas for swimming, surfing and camping right on the coast, with tides affecting access to the caves. Visitors should watch for slippery rocks and wear sturdy shoes when exploring the rock formations.

The 2018 Woolsey Fire burned through almost the entire park. Replacement equipment for the Junior Lifeguard program came as a donation from Australian surf lifeguard associations led by the Maroochydore Surf Life Saving Club, and crews spent seven months clearing debris before the campgrounds reopened.
