The White Hill and Blue Ridge Fire Roads Loop offers a dynamic touring cycling experience through Marin County's diverse landscapes. You'll pedal through pockets of California bay and coast live oak, then emerge into open grasslands that stretch towards the horizon. The route is defined by its significant elevation changes, particularly the "challenging grunt of a climb" on Blue Ridge Fire Road, which rewards your effort with expansive views from the top of White Hill, where you can see Mount Diablo and Mount Tamalpais.

This moderate 9.0-mile (14.5 km) touring bicycle route involves 1464 feet (446 metres) of elevation gain, typically taking about 1 hour and 28 minutes. The terrain is primarily wide fire roads, suitable for gravel or mountain bikes, but expect rocky and rutted sections. Spring is an ideal time to visit, as the hills burst with wildflowers like lupines and California poppies, enhancing the scenic beauty.

Beyond the panoramic views, the White Hill Open Space Preserve is known for its diverse plant life, including rare species found on serpentine rocks at higher elevations. The preserve also connects to other trail systems like Loma Alta and Camp Tamarancho, offering options for extended rides. This loop provides a solid workout and a true taste of Marin County's natural beauty for experienced cyclists.

This challenging 29.4-mile (47.4 km) touring cycling loop from Fairfax takes you on a scenic adventure through the Mt. Tamalpais Watershed, offering 4615 feet (1407 metres) of elevation gain over roughly 4 hours and 55 minutes. You'll navigate a mix of paved, dirt, and gravel roads, cycling through redwood forests and alongside the tranquil waters of Lake Lagunitas, Alpine Lake, and Bon Tempe Lake. Keep an eye out for diverse wildlife and enjoy the open views from Bon Tempe Meadow, which some describe as reminiscent of an "African savanna scene." This route is best suited for experienced cyclists ready for a demanding ride.

Before you set out, be aware that accessing these trails often requires a day-use fee for parking. While Fairfax is a great starting point, be prepared for significant climbs, including steep grades up to 10% on roads like Bolinas-Fairfax. A gravel bike or a touring bike with wider tires is highly recommended for the varied terrain, as some unpaved sections might even necessitate pushing your bike. Spring is an excellent time to visit, as the area comes alive with vibrant wildflowers.

Beyond the ride itself, this loop offers a glimpse into Marin County's history and vital infrastructure. You'll pass by historical structures like Lagunitas Dam, built in 1860, and Alpine Dam, constructed in 1917, which are key components of the Marin Municipal Water District's reservoir system, supplying 75% of the region's domestic water. The area's extensive network of multi-use trails and its connection to the birthplace of mountain biking in Fairfax add to its unique appeal.

Often busy on weekends, this is a great spot to take moment before/after summiting Mt Tam. There are spigots to fill up water and bathrooms that are open during park hours. The parking lot is very close for those that drive up. There is access to MANY trails for those on foot/bike.

This overlook designed by Mr. Bowers is one of many highway improvements that are the result of his leadership, innovation and lifelong dedication to attractive highway design, landscaping, erosion control and roadside improvements. The view of the Golden Gate Bridge from here is simply magnificent.
