The sport of bicycling starts early for many Marinites. Legions of Marin kids ride daily to school, and some join high school mountain bike teams to race locally and statewide. (Kentfield’s own Kate Courtney was crowned world champion in 2018 and competed in Tokyo Games in 2020.) Commuters ride weekdays to the ferry landings in Larkspur, Tiburon and Sausalito or across the bridge to jobs in San Francisco and beyond. And road and mountain cyclists congregate in downtown San Anselmo, Fairfax, Sausalito and Mill Valley’s Lytton Square area on weekends, clustering like colorful superheroes at local coffee spots, comparing their shiny (often pricey) steeds and trading notes before heading out for day long adventures on Marin’s roads or trails.
It’s no wonder biking is so popular in Marin County. We have an abundance of gorgeous country roads, family-friendly paths and off-road routes that make it a bona fide pedaling paradise. Every weekend, especially in spring, bicyclists stream here from all over the Bay Area to enjoy epic rides through our grassy headlands, backcountry ridges, redwood forests, oak woodlands and cliff-hugging coast. The road biking options are wide and diverse; for mountain bike and gravel bike enthusiasts, hundreds of miles of unpaved access roads and single-track trails entice knobby tired escapes into nature. It’s so much fun to ride here, it’s downright addictive.
Ready to go riding? The Marin County Bicycle Coalition (MCBC), an advocacy group, produces a detailed bike trail map that is available in laminated form with MCBC membership or at many local bike shops and bookstores. But we’ve profiled some of our favorite mountain, road and family bike rides in Marin County here.
Before you head out, however, keep in mind that some of the rides we describe bring you far into Marin’s nature wonderland, so be prepared with plenty of water, cell phone, spare tubes, tools and pumps, and be on the lookout for poison oak, yellow-jacket wasps, ticks and rattlesnakes (bobcats, coyotes and mountain lions are also present but rarely seen.) Happy trails!
Marin is the birthplace of mountain biking for a good reason: The off-road riding is simply epic. In the 1970s, a few local bike racers like Joe Breeze, Tom Ritchey, Gary Fisher and Charlie Kelly experimented with custom-built bikes, first modifying old heavy, cruiser bikes with stronger drum brakes and clusters of multiple gears that could handle the rigors of trail and dirt road riding and racing. They soon built lighter and stronger, custom-welded frames equipped with cantilever brakes, and the modern mountain bike was born. Fast forward five decades and, today, Marin is a premier destination for mountain bikers from all over Northern California and the world, drawing legions of riders each weekend.
