This trail, part of the Pacific Coast Bike Trail (PCB), is a fantastic, mostly paved two-lane bike route that follows Lagunitas Creek under towering redwood forests and runs parallel to Sir Francis Drake Boulevard on the other side of the valley. It continues south from the campground all the way to the southern exit of the Park.
