Hold on to your hat. Fort Funston features 200 foot high sandy bluffs on San Francisco's southwest coast where the winds blow reliably wildly. No surprise it is one of the premier hang-gliding spots in the country. Dog owners will be happy to know they can take leashes off here.

Everywhere you turn in this 1,200-acre greenbelt on the City's northern waterfront, you'll find endless options for relaxation and stimulation. This former military installation, with its jaw- dropping view of the Golden Gate, is headquarters for the National Park Service and the Golden Gate National Parks Conservancy.

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.
