Ridges and ravines mark this hiking area 25 minutes south of San Francisco. Wildlife, including hawks, deer, and wildflowers, abound on the slopes which drop to the Bay on one side and Thornton Beach on the other. The park's highest point is 1,200 feet and has a plaque honoring Portola's discovery of the Bay in 1769.

Offering more of a stroll than a hike, the two-mile trail that meanders through the meadows of this serene valley leads you to bluffs overlooking the Pacific. There you'll several fine sand beaches and the Pacific's shattering surf.

The long blue finger of Tomales Bay points seaward, straight along the San Andreas Fault from the north end of the Olema Valley out to the Pacific. Explore it by kayak and keep your eye for the abundant shore birds, such as herons, egrets, ospreys, and much more.

While visiting the biodiverse shorelines of the Presidio, you can’t get much closer to the Golden Gate Bridge than at Marshall’s Beach. This rugged stretch of sand and rocks is a favorite destination for photographers. Even clothing-optional sunbathers are known to frequent on warm days.

Presidio Tunnel Tops is a stunning and welcoming national park space, completely free and accessible to all!
