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.
