There's no charge for biking at this time. The trail is a short distance from the office, about halfway between it and the toll houses, on the left. Look carefully for the inconspicuous trailhead and its blue sign that reads Wm. 0.00 Start, going uphill, then leveling out. The trail is rocky but easily negotiated.
Marking is fair.
Marking is good. The trail is rocky, rooty, and rarely level, but it's suited to intermediate riders. Marking is poor. This area is low and very muddy after rain or in spring. Stay to the side.
