This is a 3,360 acre preserve with 21 miles of trails shared by pedestrians, bicycles and equestrians. Trails start at high elevation on Skyline Blvd and can go down by 1600 feet. Most of the trails are shaded by redwoods so the canyon area is moist and a good habitat for banana slugs especially in the winter. There are ferns, berries, wildflowers, coastal scrub and hardwood forests of tanoak, madrone, and Douglas fir. On a clear day, there are beautiful views of the ocean and the hills that lead down to the coast. It is recommended to bring water. The parking lot is large enough for about ten cars. There is a pit toilet less than one tenth of a mile from the start of the trail.
