San Rafael

Highlight • Settlement

San Rafael is a nerve center for urban culture with its eclectic combination of shops, ethnic restaurants, Victorian buildings, breweries, coffee shops and unique retailers. It is the oldest and largest city in Marin County and a great place to visit. If you are lucky enough to pass through town on a Sunday morning, you can taste your way through the Sunday Marin Farmers Market, the third largest in California!

San Anselmo-Fairfax Bikeway

Highlight (Segment) • Cycleway

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.

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!

Frequently Asked Questions

What kind of bike is best suited for this route?

This route offers a diverse cycling experience, transitioning from paved bikeways to unpaved watershed roads and trails. It's best suited for touring cyclists using hybrid or mountain bikes, rather than traditional road touring setups, due to the varied terrain within the Bon Tempe Lake area and Mount Tamalpais Watershed.

What is the terrain like on this cycling route?

The route features mixed terrain. The initial San Anselmo-Fairfax Bikeway sections are generally paved and easy to ride. However, once you enter the Mount Tamalpais Watershed, the terrain shifts to unpaved fire roads and dirt paths. While the loop around Bon Tempe Lake has minimal elevation changes, its unpaved surfaces require a bike capable of handling off-road conditions. Note that single-track trails within the watershed are generally prohibited for bicycles.

Are there any fees to access the Bon Tempe Lake area?

Yes, there is an $8 entrance fee for accessing the Bon Tempe Lake area within the Mount Tamalpais Watershed.

Where can I park when cycling this route?

Parking is available near the access points to the Bon Tempe Lake area. Given the $8 entrance fee for the lake area, parking is typically associated with these access points within the Mount Tamalpais Watershed. For sections along the San Anselmo-Fairfax Bikeway, you can often find street parking in nearby towns like Fairfax or San Rafael.

Is this cycling route suitable for families or beginners?

The San Anselmo-Fairfax Bikeway sections are generally easy to ride and suitable for all skill levels. However, once you enter the Mount Tamalpais Watershed, the terrain becomes unpaved with fire roads and dirt paths, which can be more challenging. While the Bon Tempe Lake loop itself has minimal ups and downs, the overall route's mixed terrain might be difficult for very young children or absolute beginners on road bikes. A hybrid or mountain bike is recommended for the watershed sections.

What is the best time of year to cycle this route?

The route can be enjoyed year-round, but consider the weather. The 'Sunnyside' of Bon Tempe Lake, with its open grassland, can get quite warm in late summer. The 'Shadyside' offers cooler oak and bay woodland. Spring and fall generally offer pleasant temperatures for cycling. Always check the local weather forecast for the Mount Tamalpais Watershed before you go.

Are dogs allowed on the trails around Bon Tempe Lake?

Around Bon Tempe Lake, you'll find views across the lake to Mt. Tamalpais, golden rolling hills, Redwood groves, and wooded areas dotted with ferns.

What wildlife might I see around Bon Tempe Lake?
