This Sausalito β€” Mill Valley Path – Alpine Dam loop from Marin City offers a varied cycling experience, blending flat paved multi-use paths with challenging road climbs and opportunities for gravel sections. You'll start with picturesque views of Richardson Bay and Mount Tamalpais from the Mill Valley-Sausalito Multiuse Pathway before ascending into the Mount Tam Watershed, where redwood forests and lakes provide a dramatic backdrop. The route culminates with panoramic vistas of the Pacific Ocean and San Francisco Bay from Ridgecrest, making it a truly iconic Marin County ride.

Rated as "difficult," this 39.5-mile (63.5 km) route involves a substantial 3794 feet (1156 metres) of elevation gain, typically taking around 4 hours and 24 minutes to complete. While the initial pathway is easy, the Alpine Dam loop introduces significant climbing, with steep and twisty sections that demand good fitness. Consider an early start to enjoy quieter roads, especially around Alpine Lake, and ensure you're prepared for a sustained effort.

Known as a "crown jewel" of Marin County cycling, this loop is celebrated for its diverse landscapes and stunning viewpoints. It offers excellent potential for gravel biking enthusiasts to integrate nearby fire roads and trails around Mount Tamalpais for an even greater mixed-surface challenge. The route also traces a former railroad corridor, connecting you to the rich history and natural beauty of the region.

A nice place, but the bike parking fee and the price of an ice cream are a complete rip off!

This tidal sanctuary runs along the Mill Valley-Sausalito Pathway and the Charles F. McGlashan Pathway. More than 400 species of migratory birds rest here after their long flights, and if you pass through in the early morning or late evening, the sunrises and sunsets reflect beautifully on the surface of this 106-acre marsh.
