Pulgas Ridge Open Space Preserve

This is a 293-acre preserve with a mix of woodland, oaks and laurel trees with the hilltop hosting a mix of grasses and non-native plants such as oleander, eucalyptus and cactus. On clear days there is a wide view of San Francisco Bay, the southern peninsula and south bay cities, and the peaks of Mount Diablo and Mount Hamilton. The elevation gain on the trails only amounts to about 300 feet, and the rate of incline is very gentle. Dogs must be on a maximum 6 foot leash except on special off-leash area.  Bicycles and equestrians are permitted on the Cordilleras and Hassler Trails only. Polly Geraci Trail is hiking only. There is no drinking water on site.
