Cycling Marin County, Mt. Tamalpais
Mt. Tam is the centerpiece of all road bike climbing in Marin County
View of San Francisco from Mt. Tam’s West Peak
Marin County is an exceptional place to climb hills and a mountain by bike. This county has it all for cycling: the Pacific Coast, riding through redwood trees past lakes, and on up to Mt. Tamalpais which offers views of San Francisco and the San Francisco Bay that beat any other location.
THE MOST POPULAR ROUTE TO THE TOP OF MT. TAMALPAIS
We have plotted five routes to the top of Mt. Tam (Alpine Dam, Muir Woods, Fairfax-Bolinas Road, Panoramic Highway, Panoramic Highway North), and Alpine Dam is the most popular by a good stretch. This climb begins at serene Alpine Reservoir in western Marin County, rides through the redwoods, along a ridgeline with the Pacific Ocean to our right, and on up to Mt. Tamalpais’ West Peak with the greatest views of San Francisco anywhere.

THE MOST SCENIC START TO THE TOP OF MT. TAMALPAIS
Cycling to Mt. Tamalpais West Peak from Muir Woods
Ride 8.9 miles gaining 2,484’ at 5% average grade.
THE MOST RUSTIC AND AGRICULTURAL BIKE CLIMB IN MARIN
Cycling the Marshall Wall East, Marin County, CA
2.8 miles gaining 553’ at 3.7% average grade.
Don’t seek this climb out for a significant challenge, as using the term "Wall" to describe this ascent is a bit of a misnomer. That being said, there is much to be seen on this climb by way of a landscape composed of almost exclusively rugged pastureland with some views of Tomales Bay, the Pacific Ocean and Marin County's Arroyo Sausal Reservoir.
THE MOST REMOTE BIKE CLIMB IN MARIN
This is an "outlier" climb by Marin County standards -- only 1,030 Strava segment attempts as of August 29, 2015 versus over 30,000 for climbs closer to "civilization" and the very popular Mt. Tam routes. However, this is an enjoyable and unique climb in a remote area of Marin where you are likely to encounter no one during your 4.4 mile trek to the top. There are great views of the Pacific Ocean and coastline to the west and one spot where we have a great view of Napa County's Mount St. Helena some 50 miles north.
