The San Diego-La Jolla Underwater Park spans 6,000 acres (24 km2) of ocean bottom and tidelands. The park's four distinct habitats make it a popular destination for snorkelers and scuba divers. The park was created by the City of San Diego in 1970 and actually has two other parks within it: the "look but don't touch" Ecological Reserve and the Marine Life Refuge.

Black's Beach is a secluded section of beach beneath the bluffs of Torrey Pines on the Pacific Ocean in La Jolla, San Diego, California, United States. It is officially part of Torrey Pines State Beach. The northern portion of Black's Beach is owned and managed by the California Department of Parks and Recreation, while the southern portion of the beach, officially known as Torrey Pines City Beach, is jointly owned by the city of San Diego and the state park, but is managed by the city of San Diego. This distinction is important as Black's Beach is most known as a nude beach, a practice that is now prohibited in the southern portion managed by the city of San Diego.
