This is the first in a series of monthly mountain bike rides around Marin showcasing the birthplace of mountain biking. It’s one of the reasons I live in Marin!
The 680 is a great trail for mountain biking in Marin County, CA. It’s a wide single track multi-use trail that runs from San Anselmo to Fairfax. Recent improvements by the Marin County Bicycle Coalition has made it even better.
