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. Although this trail is not open for walk-in use by the general public, trained volunteer trail leaders head excursions three days a week.
This Exploration created in collaboration with the Exploratorium.
