All Midpen Preserves are open to the public free of charge, 365 days a year from dawn until one-half hour after sunset.

Los Trancos Open Space Preserve is a 274-acre area located in the Santa Cruz Mountains above Palo Alto. This is an ideal spot to learn about earthquake geology. The San Andreas Fault, one of the world's longest and most active faults, splits the preserve.

Visitors can hike the easy 1.5-mile Fault Trail and learn how the mighty San Andreas Fault has shaped our landscape. The brochure-guided hike is both informational and fun for all ages.

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.
