California Top 10 Most Scenic Bike Climb

This climb is one of the five primary climb routes to the top of Mt. Tamalpais in Marin County, and may be the most scenic of them all.  The climb is mild throughout and the roadway, as with most of, if not all, Marin roads, is in great shape.  There is no shoulder to speak of, but motor vehicle traffic is light and not a real issue during this climb, you will likely encounter at least twice the number of cyclists as motorists in this part of Marin.  

The first 2.5 miles to the intersection of Bolinas Fairfax Road and Ridgecrest Boulelvard is at 6% average grade, gaining 867' along the way.
