The Alpine Dam & Mount Tamalpais East Peak loop from Downtown San Rafael is a challenging road cycling route that delivers some of the best scenery in Marin County. You'll pedal through dense redwood and oak forests, past the serene Alpine Lake and Alpine Dam, before tackling the famous "Seven Sisters" rollers. The reward for your effort is a breathtaking panoramic view from Mount Tamalpais East Peak, stretching from San Francisco to the Pacific Ocean.
This difficult 40.6-mile (65.4 km) ride, with its 4348 feet (1325 metres) of elevation gain, is a serious undertaking, typically taking around 3 hours and 40 minutes. The route is primarily on paved roads, though some sections can be steep and twisty, particularly on Fairfax-Bolinas Road. It's a demanding ride best suited for experienced cyclists with excellent fitness levels.
Widely considered a "crown jewel" among Marin County road cycling routes, this loop is often cited as one of the most scenic ways to experience Mount Tamalpais. The journey itself, with its varied microclimates and iconic landmarks like the Seven Sisters, is as much a highlight as the destination. It's a true bucket-list ride for those seeking an advanced road cycling experience near Downtown San Rafael.

Embark on the difficult Bolinas Lagoon & Seven Sisters loop, a challenging road cycling adventure spanning 40.5 miles (65.2 km). This route immerses you in diverse scenery, from the serene coastal wetlands of Bolinas Lagoon, where you might spot harbor seals and various bird species, to the forested hillsides. You will conquer a substantial 4876 feet (1486 metres) of elevation gain, with the iconic "Seven Sisters" section of Ridgecrest Boulevard providing undulating terrain and panoramic vistas of the Pacific Ocean, Stinson Beach, and Bolinas Bay. Plan for approximately 3 hours and 52 minutes of intense riding.
This demanding route requires very good fitness due to its significant climbs and sustained effort. As you transition from the coast to higher elevations, be ready for varied microclimates and potential shifts in weather. Always ensure your racebike is in excellent working order to handle the challenging terrain effectively. Starting your ride earlier in the day can often provide more favorable conditions and less traffic.
The Bolinas Lagoon itself is an ecologically significant tidal estuary, making it a prime spot for nature observation. The route's journey through Mount Tamalpais State Park highlights the region's natural beauty and offers a unique perspective on its varied landscapes. This loop is a notable choice for experienced cyclists seeking a rewarding physical challenge combined with stunning natural surroundings.
