October 12, 2025, Marin Museum of Bicycling

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.

Johnny Doughnuts is the go-to place if you have a sweet tooth and have been lucky enough to enjoy a handcrafted offering from one of their food trucks at another location in the Bay area. They offer organic coffee and teas to accompany everything from a classic raised doughnut to caramelized apple fritters, wild-berry-jam-filled bismarks, and "crodoughs," a delicious creation of a croissant crossed with a doughnut!

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!

The view from the start of this trail is amazing with the rolling hills leading into the mountains. There is lush greenery as far as the eye can see as Mount Tamalpais Watershed meets the Cascade Canyon Preserve.
