Fairfax

Highlight • Settlement

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!

Best appreciated after winter rainfall, this waterfall is right along Old White Hill Grade trail. If surprised by a shower the massive pipe channeling the usually small trickle of water under the trail can serve as an emergency roof, but be careful if water levels increase suddenly ...
