Discover more about Pulgas Ridge Open Space Preserve

Pulgas Ridge Open Space Preserve, a 366-acre sanctuary managed by the Midpeninsula Regional Open Space District (MROSD), offers a refreshing escape into nature. Located in the hills above Redwood City and San Carlos, California, this preserve 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 surrounding peninsula. Historically, the land was once home to the Hassler Health Farm, a tuberculosis sanitarium owned by the City of San Francisco. Established in 1927 as the San Francisco Health Farm, it was later renamed in 1931. The facility expanded in the early 1940s with the help of the Works Progress Administration (WPA). The sanatorium closed in 1964 and was repurposed as a hospital for the indigent before finally closing its doors in 1972. The buildings were demolished in 1983, and MROSD acquired the property, transforming it into the open space preserve it is today. Remnants of the past, such as old retaining walls and steps, can still be found 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 17.5-acre off-leash area, a rare and cherished amenity in the Bay Area. This expansive, 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 cleanliness and natural beauty. Pulgas Ridge offers a variety of trails to suit different fitness levels and interests. The Cordilleras Trail, located near the preserve entrance, is a relatively flat, easy trail suitable for wheelchairs and strollers. It meanders through a meadow and along Cordilleras Creek, providing a gentle introduction to the preserve's natural environment. 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. The Dick Bishop Trail connects the Polly Geraci and Blue Oak Trails, offering an alternative route that avoids the off-leash dog area. In spring, Pulgas Ridge comes alive with a vibrant display of wildflowers. Indian warrior, hound's tongue, mule's ears, and milkmaids are among the many species that carpet the hillsides, creating a colorful spectacle for visitors to enjoy. Keep an eye out for deer and other wildlife that call the preserve home. While exploring Pulgas Ridge, be mindful of the potential presence of poison oak and ticks. Wear appropriate clothing, stay on marked trails, and check yourself and your pets for ticks after your visit. Remember to bring water, as there are no drinking water sources within the preserve. Whether you're seeking a challenging hike, a peaceful nature walk, or a place to let your dog run free, Pulgas Ridge Open Space Preserve offers a diverse and rewarding outdoor experience. Its convenient location, varied terrain, and stunning views make it a popular destination for locals and visitors alike. The preserve is open from a half-hour before sunrise to a half-hour after sunset, providing ample opportunity to explore its natural wonders.
