San Buenaventura State Beach, State beach in Ventura, California, United States

San Buenaventura State Beach is a beach in Ventura, California, with its main entrance at 901 Pedro Street off the 101 Freeway. It lies next to the 1,700-foot Ventura Pier, which has a snack bar and restaurant. The beach has picnic tables, barbecue grills, volleyball courts, restrooms, and equipment rentals.

The area was originally inhabited by Chumash Native Americans who established settlements along this section of the California coast. European contact and subsequent development transformed the region over the following centuries.

Events at the beach include the Pirate Festival, a triathlon, the "Seaside Invitational" cross country meet and volleyball tournaments. Each summer the State Junior Lifeguards Program trains young participants here. The beach is also the start of the Omer Rains Bike Trail, which leads to other nearby beaches.

The main entrance is at 901 Pedro Street, just off the 101 Freeway, and the beach sits beside the 1,700-foot Ventura Pier, which has a snack bar and restaurant. The flat sand and the paved Omer Rains Bike Trail make it easy to reach the water and the neighbouring beaches on foot or by bike.

The Omer Rains Bike Trail begins here and links the beach to other nearby beaches; the source does not give its length. The beach is also a monitored nesting site for the snowy plover, with temporary signs and fences around nests in breeding season, and nonnative vegetation has been cleared to protect the dunes.
