This ride begins on the San Francisco side of the Golden Gate Bridge. After crossing the bridge, the route takes you up the main paved road toward the bunkers at the top and then down the other side to Fort Cronkhite and Rodeo Beach. After a short stop at the beach, you hit the trails, climb over a hill on fire roads and then descend into Tennessee Valley, a major jumping-off point for visitors to the area. Another climb on Marinchello Trail leads to panoramic views toward Sausalito, Angel Island and Richardson Bay, before dropping down yet again near Fort Cronkhite. One final climb takes you back over a hill and down to the bridge for your return to where you started.
The trails are wide, generally smooth and not terribly steep. There are four distinct climbs along the route, however, and that's what makes the ride rather strenuous.
Start the ride at the San Francisco side of the Golden Gate Bridge, on Merchant Road very near to the toll booth. To get there, take Highway 101 as if you were going to go north across the bridge. Get off at the vista point at the toll booth, go through the parking lot and turn right on Lincoln Boulevard. Cross under the bridge approach road, turn right on Merchant Road and park near the bridge toll booth.
If you are coming from the North Bay, begin the ride at the north side of the bridge and pick it up at the 2.2 mile marker point.
