Start of the climb.

This is the most challenging climb in Marin County and boasts an impressive 5.02 FIETS index, well above any other climb in the county.  Beginning in the popular coastal town of Stinson Beach (provisions available at the Stinson Beach Market about a half mile to the north on Highway 1 from the climb start point).

Mt. Tamalpais is the highest peak in the Marin County and has two peaks -- the East Peak (2,574'), and West Peak (2,563').  The white radar dome that sits upon Mt. Tam's slightly lower western peak is quite discernable from afar.  

The climb is divided into three parts:

1.   Panoramic Highway from Stinson Beach:  This portion has some great views of the Pacific Ocean to the west, giving way to Redwood trees bordering the highway for several miles until near the top and just shy of Pantoll Campground and Mt. Tamalpais State Park.  ​There is a Visitor Center here where maps and  information about the area are gladly dispensed by Park Rangers. There is water at this location. The statistics for this section of the climb are 3.6 miles / 1,375' gained / 7.3% average grade.

2.   Pantoll Road: ​The second leg is up Pantoll Road from its intersection with Panoramic Highway, to Rock Springs Parking Area (staging area for several truck television commercials).  Along this route we have great views down to the Pacific Ocean and, as we climb higher, of Mt. Diablo, the San Francisco Bay and San Francisco.  This segment is 1.4 miles / 490' / 6.2%.

3.    Ridgecrest Boulevard: ​The final leg is along Ridgecrest Boulevard East.  This portion is the easiest of the three, and gives us more spectacular views of Mt. Diablo, the San Francisco Bay, and San Francisco.  This segment ends as Ridgecrest "crests" just east of the radio dome atop Mt. Tam’s West Peak, and is 1.5 miles /510’ / 6.8%.

A very pleasant, and challenging, 46 mile route that captures the two top climbs in Marin County begins from the south end of the Golden Gate Bridge, across the Bridge, through Sausalito and Mill Valley, down to Muir Woods, back up to Panoramic Highway (follow Panoramic Highway from its southern intersection, Muir Woods Road and Panoramic Highway, to its northern point at Stinson Beach on Highway 1, a total of 8.1 miles), up to the top of Mt. Tam and then follow the route back to San Francisco.  See PJAMM Cycling’s Golden Gate Bridge Page and also its RideWithGPS map for more details.
