NOTE: Reservations required to access this trail. Trained volunteers head excursions three days a week. Local nature lovers can enjoy the rare opportunity to hike, bike, or ride their horses through pristine stands of old growth Douglas Fir, evergreen and fragrant coastal scrub while enjoying ridge-top vistas of our watershed lands, reservoirs, the Pacific Ocean and San Francisco Bay. Small groups of hikers, bicyclists, or equestrians can now make reservations for guided excursions along the Fifield-Cahill Ridge Trail. Because of environmental restrictions within the fragile ecosystem, groups must be accompanied by a volunteer trail leader and are limited to approximately 20 people (fewer on horseback), scheduled no more than three times a day on Wednesdays, Saturdays, and Sundays. You can reserve spaces for as many as five people for any one event. Sign up for an event using the online reservation system. For more information visit:
