Climb Summary


Tomales Bay and Marshall Wall West climb just off center right.

The Marshall Wall West and East climbs are located in the northwestern corner of Marin  County and are quite rural and remote.  The landscape is almost  exclusively rugged pastureland with some views of Tomales Bay, the Pacific Ocean  and Marin County's Arroyo Sausal Reservoir.  The climbs can easily be fit into 50 mile or less loops that begin in Novato or Petaluma, with the midpoint from either start the quaint coastal town of Point Reyes Station.  Here is a nice 36 mile loop used for the annual Team Swift Youth Cycling Club fundraiser.


This is the northernmost Marin county cycling climb.

Start at the intersection of Marshall-Petaluma Road and Highway 1.


Now there’s an indicator of how popular this route is for cyclists.

This is dairy country.

Spectacular scenery as we climb, with beautiful colors during springtime.

Do not seek these climbs out for a significant challenge, as the term "Wall" to describe these ascents is a bit of a misnomer.  The Marshall Walls are tame by comparison to other more appropriately named climbs in the North Bay (such as Rancheria and Pine Flat Walls).

Traffic/Roadway Surface:  There is very little traffic along this rural, narrow, two-lane roadway, but you may encounter very large milk transport trucks (slideshow,  above) -- this is dairy country, after all!  As with most of the Marin County roads, this one is in great shape.  

That’s a wrap!
