This bikeway offers a better alternative to the much busier Center Boulevard, which does not have a shoulder and an even better route than the Sir Francis Drake Blvd highway. Lansdale and San Anselmo Avenues are quiet residential streets that run parallel and provide a pleasant passage through town away from busy traffic.

This town, nestled in the forested hills among unspoiled open space in Marin County, is a nice respite from the large nearby metropolis. It is a quirky, hip place with a small-town vibe filled with restaurants, music venues, and independent shops. Fairfax is home to many musicians who live here, and on any given night, you can find live music featuring local and national touring acts jamming in a relaxed, casual atmosphere. It has a very cycle-friendly culture, and be sure to take the time to visit the Museum of Bicycling while you are here!
