Southern California
Black Beach Torrey pines/ La Jolla
Excellent peach wide open, great sand, great water, lots of people.
In my opinion, not great for play, as naturist, won't be shy about confronting you if they think you're messing up their textile free experience.
San onofre trail 6.
Wild spectacular Coast, think the end of the original planet of the apes on the beach. Technically was closed as a nude beach back in 2008. However, everyone sneaks over the fence onto the camp Pendleton Beach. Biggest drawback, mostly guys And pretty deserted.
there's also a spectacular Beach up in San Francisco that's on the Pacific side of the Golden gate bridge. Although last time I was in the area they had created a new path down to the beach close to the bridge. So I'm not quite sure how active it is currently as a nude beach.
