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!

Mount Tamalpais Summits

Highlight (Segment) • Summit

Mount Tamalpais is the highest peak in the Marin Hills, which are part of the Northern California Coast Ranges. The elevation at the West Peak, its highest point, where a radar dome currently stands, is at about 2,576 feet (785 m). It stood over 2,600 feet (792 m) before the summit was flattened for the radar dome construction. The East Peak, the mountain's second highest peak, is 2,572 feet (784 m). The mountain is clearly visible from the city of San Francisco and the East Bay region.

The majority of the mountain is contained in protected public lands, including Mount Tamalpais State Park, Muir Woods National Monument, and the Mount Tamalpais Watershed. It adjoins the Golden Gate National Recreation Area (which in turn adjoins Point Reyes National Seashore) as well as several Marin County Open Space Preserves. This provides nearly 40 miles (64 km) of continuous publicly accessible open space.
