INTRO

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 the Pacific Ocean and Marin County's Arroyo Sausal Reservoir.  This climb begins just off Hwy 1 and climbs past a neat old church and quickly into ranch and dairy land.  Looking back along the first mile of the ride we have some nice views of Tomales Bay. 
Average grade is 4.4% (5.6% for climb only).  15% of the route is descent, 31% 0-5% grade, 47% 5-10% and 6% is at 10-15% grade.  The steepest quarter mile is 9.4%.

Traffic:  Minimal - you are more likely to encounter a milk transport semi-truck and trailer than automobile.

Really nice views of rolling open farmland and lots and lots of cows. Brought back memories of the Pyrenees! Very few cars along the ten miles on this road but road surface could be better with potholes mostly patched up. Steepest part of the climb was the kicker turning off of Highway 1.

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.

There’s not much traffic on this ride, but . . .you know it when there is.

View west from the finish.

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).

Roadway Surface and Traffic Report:  There is very little traffic along this rural, narrow, two-lane roadway, but you may encounter very large milk transport trucks (see 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!
