When the fog hasn't rolled in, this expansive stretch of sand is about as close as you can get in Marin to the stereotypical feel of a Southern California beach. There are several clothing-optional areas, among them a section called Red Rock Beach. Swimming at Stinson Beach is recommended only from early May through September, when lifeguards are on duty, because the undertow can be strong and shark sightings, although infrequent, aren't unheard of. On any hot summer weekend, every road to Stinson is jam-packed, so factor this into your plans. The down-to-earth town itself—population 600, give or take—has a surfer vibe, with a few good eating options and pleasant hippie-craftsy browsing. Amenities: food and drink; lifeguards; parking (free); showers; toilets. Best for: nudists; sunset; surfing; swimming; walking.
