Fully Nude? Yes

Known as one of Southern California's most popular surfing destinations, Black's Beach is the largest nude beach in the United States, making it an extremely popular destination for naturalists. However, nudity has been prohibited on the city portion of the beach since 1977. You can shed your clothes on the state-owned portion, though, which starts about 100 yards south of the trail leading to the Torrey Pines Gliderport, and extends for about a mile. Limited amount of real estate, but when you're looking for naked California girls, you take what you can get.
