 In 1976, the People of the State of California adopted the Coastal act, making the area below the mean high tide a condominium of the County and the California Coastal Commission, and the Coastal Act required beach access for all California beaches, meaning there is a constitutionally-guaranteed right of way through the State Park property to the beach of the Federal Enclave.Because the beach above the mean high tide is a Federal enclave and not part of Angel Island State Park, like Baker Beach in the Presidio of San Francisco, it is not subject to local ordinances.There is no federal or statewide law prohibiting nudity.
