Ocean Beach Park

Ocean Beach Park sits at the mouth of the Santa Ynez River, about 13 miles west of Lompoc on the Vandenberg Space Force Base coastline. The shoreline is wide and wind-scoured, backed by a tidal estuary, and the park is one of the more remote public beaches in Santa Barbara County. Vandenberg owns all the surrounding land, so the park can close on short notice for base operations or when winter storms flood Ocean Avenue.

The Santa Ynez River is the largest river entirely within Santa Barbara County, and its estuary is the defining feature here. In winter the river breaks through the sand berm and runs out to the ocean, and through summer the berm rebuilds and the lagoon sits closed behind it. The wide lagoon is a noted birding location. The estuary has been closed to public water access for over 40 years to protect endangered species, so boating, fishing, and swimming inside the lagoon are all prohibited. The beach itself also closes entirely from March 1 through September 30 each year for snowy plover nesting, leaving a five-month window of legal access.

The exposed sandy shoreline and breaking surf put Ocean Beach Park in the surf zone biome. The Santa Ynez River estuary behind the beach is a bay biome, accessible by walking near but not by entry. Snorkeling and scuba diving are not reported here.

Parking is free in the lot at the end of Ocean Avenue, open from 8 a.m. to sunset. Take is prohibited within the Vandenberg State Marine Reserve, which covers the entire park, so all fishing and spearfishing are illegal here.
