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

The Preserve features an easy-access trail and a dog off-leash area. The Cordilleras Trail, which is designed to accommodate wheelchairs, strollers, or visitors desiring a less strenuous open space experience, adjoins the parking lot and travels through a meadow to a bench located in a quiet, wooded area by Cordilleras Creek.

Across the creek, the one-mile Polly Geraci Trail ascends an oak-covered hillside to the top of the Preserve, where vegetation changes to chaparral, providing a great place to enjoy the view. The Polly Geraci Trail meets the paved Hassler Trail, which in turn connects to the Blue Oak Trail and Cordilleras Trail, creating an easy two-mile loop. Visitors may let their dogs roam off-leash in the 17.5-acre area in the center of the Preserve.

The 2-mile Dusky-footed Woodrat Trail reaches from the western end of the Hassler Trail, ascends to the ride that adjoins San Francisco Water Department lands, and descends to the easternmost end of the Cordilleras Trail.

The Dick Bishop Trail, named in memoriam of a former District Board member, extends from the Blue Oak Trail through the Preserve’s south canyon, and eventually connects with the Polly Geraci Trail.
