This 366-acre site has trails for hiking and dog walking, including a 17.5 acre off-leash area. Enjoy expansive view of the Bay and surrounding hillsides.
In early spring, look for wildflowers such as Indian warrior, hound's tongue, mule's ears and milkmaids.
The six miles of trails in Pulgas Ridge Open Space Preserve offer a mix of cool canyons and lofty views. The area was once the site of the Hassler Health Home, a tuberculosis sanitarium owned by the City of San Francisco. In 1983, the area was purchased by the Midpeninsula Open Space District. The sanitarium was demolished in 1985 to return the land to open space, however visitors can still find the remains of buildings, including rock retaining walls and steps.
