Trail Notice

Construction of the new Franciscan Loop Trail route has been completed, and the trail is now opened to the public.

Due to potentially hazardous trail conditions, a section the Franciscan Loop Trail was removed and restored by District crew members.

The trail was rerouted in order to avoid trees that have been identified as having an increased risk of falling on the trail.


Enjoy the 1.5-mile self-guided tour the San Andreas Fault Trail.

Los Trancos

Los Trancos Open Space Preserve is situated at about 2,000 feet and always has fresh air scented with pungent bay leaves, sweet grass, and damp woods. Here, visitors will find a pleasant environment of rolling grassland knolls alternating with oak woodland and cool shaded forest. On a clear day, one can spot the gleaming skyscrapers of San Francisco and pick out Mt. Diablo across the bay. A five-mile trail system is available for visitor enjoyment.


The preserve's entrance is on Page Mill Road, 7 miles west of Highway 280 and 1.5 miles east of Skyline Boulevard. Parking is available for 20 vehicles. Additional parking and restroom facilities are available at the Monte Bello Open Space Preserve parking area, located directly across Page Mill Road.
