Fall on the Watershed: Explore the Ridge Trail

Almost any time is good for hiking or cycling the Peninsula Watershed’s Fifield-Cahill Ridge Trail. 

Old-growth Douglas fir known as "Old Doug"

But our crisp, clear fall days can make for a particularly exhilarating hike or bike ride along part—or all—of the approximately 11-mile stretch through old-growth conifer forest, fragrant coastal scrub, grassy serpentine ridge tops, and other native habitats.

Public access is available by reservation on selected Wednesdays, Saturdays and Sundays, with scheduled Ridge Trail events ranging from easy strolls to fitness hikes or rides. All of them are led by trained trail leader volunteers, and are limited to about 20 participants.
