15 Outdoor Spots You Won't Believe Exist in the Heart of San Francisco​

Whether or not you're a lighthouse fanatic, the Point Bonita Lighthouse is yet another Marin must see. Originally built in 1855, this lighthouse has long been referred to as the "Crown of the Bay" and is still in active use today.

While it is maintained by the United States Coast Guard, the National Park Service provides access to visitors. If you're interested in discovering Point Bonita for yourself, be sure to plan ahead, as it's only open on Saturdays, Sundays, and Mondays.
