Marin Headlands Professional Guide
Detailed Trail Description from our Guidebook
"The Golden Gate National Recreation Area includes what is more commonly known as the Marin Headlands. The hills of the headlands, easily seen on the west side of Highway 101 across the bridge from the city, are home not only to the decaying battlements, but also to many trails and fire roads which meander across them and through the canyons of this public-use land. Long a favorite of San Francisco hikers and equestrians, the Marin Headlands has more recently become a play area for the many mountain bike enthusiasts of the Bay Area. The trails are wide, generally smooth, and not terribly steep. There are four distinct climbs along the route however, and that is what makes the ride somewhat strenuous."
