Picture a 3.5-mile stretch of white beach with few tourists and no highrises. It's just you and the waves and the seabirds at Ocean Beach, on the westernmost border of San Francisco, adjacent to Golden Gate Park. 

Infamous for its maximum security prison, Alcatraz is also known for remnants of an 1850s military fort, the West Coast's first lighthouse, the birthplace of a Native American movement, an important bird-nesting locale, and the historic Alcatraz Gardens.

It's hard to believe such a vast, beautiful, and diverse wilderness is so close to a major metropolitan area. The Marin Headlands is a crown jewel of the Golden Gate National Parks, abounding with places of natural wonder and beauty (Rodeo Valley/Lagoon, Gerbode Valley, Hawk Hill, Tennessee Valley) and remarkable historic sites (Point Bonita Lighthouse, Fort Cronkhite, Nike Missile Site, Battery Townsley).

Windswept, exhilarating, and covered with unique red and green pebbles, this beach is just three miles northwest of the Golden Gate Bridge.
