South Beach at Leo Carrillo State Park is a sandy spot near the mouth of a creek that flows out (rarely) from Arroyo Sequit. This dry wash drains part of the Santa Monica Mountains in Western Malibu.
Several sea caves and tunnels can be found in the rock walls at Sequit Point and they are the real highlight of this beach. Some of these caves are only exposed at low tide and others are higher above the surf, but watch kids if they are exploring the point. At low tide there are excellent tide pools to explore at South Beach. The southern part of this cove is Nicholas Canyon County Beach which you can walk to, except at high tide.
Dogs are not allowed at South Beach, but they are at North Beach north of lifeguard tower number 3 if they are on a leash.
South Beach at Leo Carrillo State Park is across Pacific Coast Highway (Hwy1) from the main parking lot just inside the toll booth entrance. Near this parking lot there is a popular large campground and a beach access trail that goes under PCH to South Beach. Hiking trails also start at this parking lot and take hikers inland into the state park and even farther to Nicholas Flat Natural Preserve. Some of these trails are wheelchair accessible.
Note that if you don’t want to pay the entrance fee, and if you get lucky, there might be free spots along PCH near the park entrance.
