Project Background

The Fifield-Cahill Ridge Trail Opened in 2003. The 10-mile trail extends from the Skyline Quarry at Highway 92 to the north SFPUC peninsula watershed boundary, where it connects with the Golden Gate National Recreational Area trail system and Sweeney Ridge. The objective of the Southern Skyline Boulevard Ridge Trail Extension Project is to provide public access to the Peninsula Watershed and enhance educational opportunities while ensuring watershed protection.

Members of the public can make reservations online for volunteer-led excursions on the trail for hikers, cyclists, and equestrians three days a week. https://sfpuc.org/learning/come-visit/fifield-cahill-ridge-trail
