Features

  • Wandering the trails in early spring, visitors will see many wildflowers, such as Indian warrior, hound's tongue, mule's ears, and milkmaids, in addition to three members of the lily family: fetid adder's tongue, giant trillium, and mission bells. Pulgas Ridge is home to about 90 native species of trees, shrubs, ferns, and flowers.

Off-Leash Dog Area 17.5-acre Off-Leash Dog Area

Visitors can let their dogs off-leash in the 17.5-acre area located in the center of the Preserve, accessible from the Cordilleras Trail, Polly Geraci/Hassler Trails, and the Blue Oak Trail. While in this area, visitors must have a leash in their possession and their dog must be under voice control.

Note: Area is fenced and signed at entrances, but there is no fencing around the off-leash area.

Trails

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. The trail extends 0.8 miles at a very slight grade. The first part of this trail parallels a paved road. This paved road continues to the top of the hill and the grade exceeds 10% and may be too steep for wheelchair use. The accessible trail leads away from this road, bringing visitors into a quiet wooded valley with a delightful little clearing and bench, next to the 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.

Trail Conditions

  • The cutover trail from the Preserve parking lot to the Cordilleras Trail is now OPEN.

History

Formerly the site of the Hassler Health Home, a tuberculosis sanitarium owned by the City of San Francisco, the area was purchased by the District in 1983. Neighbors of the Preserve contributed to the land's protection when they approved a special assessment to help fund the purchase. The sanitarium was demolished in 1985 to return the land to open space. Observant visitors may see remnants of the buildings, including rock retaining walls and steps.
