Embark on a difficult road cycling adventure from Downtown San Rafael, looping through Alpine Dam and up to Mount Tamalpais East Peak. This challenging route spans 40.6 miles (65.4 km) and demands a significant 4348 feet (1325 metres) of elevation gain, typically requiring about 3 hours and 40 minutes to complete. You will cycle through dense redwood and oak forests, past the serene waters of Alpine Lake, and tackle the famous "Seven Sisters" rollers before reaching panoramic views from the East Peak.
Given its difficult rating, you should have very good fitness before attempting this ride. While the route is mostly well-paved, be aware that some sections have been reported to have broken pavement in the past, though many areas have since been repaved. Always check current road conditions before you head out to ensure a smooth and safe experience.
This loop offers a quintessential Marin County cycling experience, combining the natural beauty of Mount Tamalpais State Park with the thrill of a demanding climb.

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.
