Embark on an adrenaline-fueled mountain biking adventure through Big Rock. The trail reaches its peak at the towering landmark, a colossal rock that adds a unique touch to the experience. Exercise caution on the descent; the pavement can get slippery, adding an exhilarating challenge to this thrilling ride.

This trail, part of the Pacific Coast Bike Trail (PCB), is a fantastic, mostly paved two-lane bike route that follows Lagunitas Creek under towering redwood forests and runs parallel to Sir Francis Drake Boulevard on the other side of the valley. It continues south from the campground all the way to the southern exit of the Park.

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!
