Alpine Dam + Mt. Tam

Cycling Route

Details
86.44 km
1,660 m
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.
