Baker Beach is a very popular urban beach in San Francisco that offers a nude naturist area and a great view of the Golden Gate Bridge. The mile-long beach sits at the base of cliffs, with various hiking trails along its side. There are 2 historical coastal artillery batteries close by & a small carpark to the south with public restrooms
You’ll see a very clear ‘Hazardous Surf’ sign on the beach which not only indicates how risky it can be to take a dip in this cold water but also marks the boundary of the clothing-optional zone. Make sure you don’t disrobe until you’re north of the sign.
