An absolute must-see for cycling enthusiasts! This museum in Fairfax tells the story of nearly 200 years of cycling history, from 19th-century velocipedes to modern racing bikes. It's also home to the Mountain Bike Hall of Fame, featuring unique specimens and stories about the pioneers of mountain biking. The collection is impressive and authentic—no replicas, but real bicycles that showcase the evolution of technology and design. An inspiring place where you can truly feel the passion for cycling.

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!

There is a great view of the northern point of Alpine lake where a small channel feeds over to Bon Tempe Lake. This is a great place to drop a line, or just enjoy the aquatic views.
