Escape the bustle of Silicon Valley at Pulgas Ridge Open Space Preserve, a 366-acre sanctuary in the hills above Redwood City and San Carlos. This natural retreat boasts six miles of trails that wind through diverse terrains, from cool, shaded canyons to ridge tops with sweeping views of the San Francisco Bay and the Santa Cruz Mountains. Historically, the land was once home to the Hassler Health Farm, a tuberculosis sanitarium owned by the City of San Francisco. Established in 1927, the facility expanded in the early 1940s and closed in 1972. The buildings were demolished in 1985, and the Midpeninsula Regional Open Space District (MROSD) acquired the property, transforming it into the open space preserve it is today. Observant visitors can still find remnants of the past, such as old retaining walls and steps, particularly off the Hassler Trail, adding a touch of historical intrigue to the natural landscape. The preserve is particularly popular among dog owners due to its expansive 17.5-acre off-leash area, a rare and cherished amenity in the Bay Area. This fenced area allows dogs to roam freely, socialize, and explore under the supervision of their owners. Outside the designated off-leash zone, dogs are welcome on all trails but must be kept on a leash. Remember to bring waste bags and practice responsible pet ownership to help maintain the preserve's beauty. Pulgas Ridge offers a variety of trails to suit different fitness levels and interests. The Cordilleras Trail provides a less strenuous, wheelchair-accessible experience through a meadow and along Cordilleras Creek. For a more challenging hike, the Dusky-footed Woodrat Trail traverses the northern portion of the preserve, offering a strenuous climb and rewarding views. The Polly Geraci Trail ascends an oak-covered hillside, transitioning into chaparral vegetation and providing vistas of the Santa Cruz Mountains. In the spring, Pulgas Ridge comes alive with a vibrant display of wildflowers.
