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.

At this point on Sky Oaks Road, there is a junction with Shaver Grade Road, which connects with a dense network of trails and dirt roads near Bald Hill in the Mount Tamalpais State Park.
From here, you can continue on the paved Sky Oaks Road or go arond the gate on to the gravel Shaver Grade Road.

In 1967, the family of Natalie Coffin Greene gave 25 acres of Phoenix Lake land for a park in her memory. Locals know about the little park at the end of Lagunitas Road in Ross, although they may not know its name. Most people think of it as the shady little park just below Lake Phoenix, and the place to park your car and set off on a hike or or mountain bike ride on the extensive Marin Municipal Water District’s watershed lands and Mt. Tamalpais. It is a very private, secluded and peaceful spot to set out on a day hike or bike ride. The park also makes a great destination in and of itself. It has picnic tables, Ross Creek running through it, and restrooms.
The fire road up to Phoenix Lake continues around the north side of the lake, and connects with fire roads running throughout the watershed lands up to the top of Mt. Tam. The south side of the lake is strictly a hiking trail, so no bikes allowed. However, dogs are allowed as long as they are on leash. The round trip walk from the park up and around the lake is about 2.7 miles.
The tiny parking lot is usually full on summer weekends, so it's better to bike in. Up at the lake, there are a couple of benches for relaxing and enjoying the view and the quiet; you can also fish, but there are no people or boats allowed in the water, which would be nice to cool off in the summer!

Quieter albeit slightly higher and steeper climb out of Mill Valley to Panoramic Highway instead of climbing on Hwy 1, meandering along lesser traffic neighborhood streets with more shade and awesome bay views.
