The Sausalito — Mill Valley Path – Bothin Marsh Preserve loop offers a fascinating gravel biking experience, blending smooth paved sections with the potential to connect to more rugged terrain. You'll pedal alongside the serene Richardson Bay, with Mount Tamalpais as a constant backdrop, and pass through the ecologically rich Bothin Marsh Preserve, a haven for migratory birds. The route provides a unique perspective on the Marin County coastline, eventually revealing distant views of San Francisco and the iconic Golden Gate Bridge.
This difficult 19.8-mile (31.9 km) loop, with 1979 feet (603 metres) of elevation gain and an estimated duration of 2 hours and 21 minutes, is ideal for experienced gravel riders. While the core pathway is accessible, the overall difficulty rating reflects the potential for integrating with more challenging gravel routes in the wider Marin County area. Parking is available near the Marin City starting point, but be mindful of potential flooding in the Bothin Marsh section during king tides.
This route is more than just a ride; it's a crucial non-vehicular link between Sausalito and Mill Valley, highlighting the ecological significance of the Bothin Marsh Preserve. It's a living example of climate change adaptation efforts, with ongoing projects addressing sea level rise impacts. For those looking to explore Marin County's gravel biking opportunities, this loop serves as an excellent starting point, connecting you to a network of diverse terrains and stunning natural features.

When you think of the iconic features of San Francisco, the Golden Gate Bridge is one of the first things that comes to mind.

Traveling along the Bridge can be cold, windy, and foggy, even in the summer, so dress appropriately. At the south end, you can purchase a souvenir at the Golden Gate Bridge Pavilion and visit the café next to the visitor center. Restrooms are at both the north and south ends, and cyclists have toll-free access to the Bridge's sidewalks 24 hours a day. A bike ride across this extraordinary Bridge is an adventure you don't want to miss!
