This secluded cove at the northernmost end of Baker Beach is San Francisco’s not-so-secret nude beach. It was originally established by gay men who shimmied down the steep cliff side in their skivvies to get to the private area. Since the addition of a trail and stairway nearly a decade ago, Marshall's now attracts open-minded nudists of all kinds. Some go to sunbathe and soak up the scenery, others construct stacked driftwood nooks for canoodling. The scene tends to be more risqué closer to the Golden Gate Bridge. But only at Marshall’s can you get close this close to the bridge itself.
