|About the Ride|
|During World War II the nation’s defenses included major anti-aircraft installation along the Pacific Coast to protect against attack from foreign aircraft. Some remnants of those times are present today just north of San Francisco across the Golden Gate Bridge.|
|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 route of this ride begins on the San Francisco side of the Golden Gate Bridge, since that side is where most of the users of Marin Headlands come from. It could just as easily begin on the Marin side, since there is plenty of public parking available there as well. After crossing the bridge, the route leads up along the main paved road toward the Battery 129 at Hawk Hill and then down the other side to Fort Cronkhite and Rodeo Beach. After a short stop at the beach, you get back on the trails and climb the hill along Miwok Trail to then descend into Tennessee Valley, the main jumping-off point for the headlands. Another climb along Marincello trail yields panoramic views of Richardson Bay and Sausalito before dropping down again near Fort Cronkhite. One final climb takes you back up to the road leading back to Golden Gate Bridge.|
|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.
|Start the ride on the San Francisco side of the Golden Gate Bridge, on Merchant Road near the toll station. To get there, take Highway 101 as if you were going north across the bridge. Get off at the vista point right at the toll booth, go through the parking lot and then turn right onto Lincoln Boulevard. Cross under the bridge approach road and turn right on Merchant Road. Park along the road.|
|If you are coming from the North Bay, begin the ride at the north side of the bridge and pick up the directions at the 2.2 mile point.|
