When it comes to riding in Marin County, the Alpine Dam Loop is second to none. After meandering through a handful of friendly towns, the road turns uphill— and that's when this loop really begins to set itself apart. This ride is all about pleasure and pain, combining fantastic views and scenery with challenging climbs and wicked descents.
