This trail is not to be confused with the easier Buck Hollow hike which is hiked in the opposite direction.
From the parking area on 211 head up the trail crossing the stream and go left to the blue blazed Buck Ridge trail. The first 1/2 mile is very steep and has more than 660 steps. Continue up the mountain passing a rock overlook until you come to a tee in the trail. Go right on the yellow blazed Hazel Mountain Trail for to the Hazel Mountain parking area.
At this point you can either continue up to Mary's Rock or shorten the hike by 3.0 miles and turn right on the blue blazed Buck Hollow trail.
To continue up to Mary's Rock cross Skyline Drive, walk 50 yards left uphill and head uphill on the Meadow Spring Trail for 0.6 miles passing the ruins of an old homestead about halfway before meeting the intersection of the white blazed Appalachian Trail and ridge line.
Turn right on the AT following it for 0.8 miles before arriving at the junction of the Mary's Rock Lookout Trail. Turn left uphill on the Mary's Rock Lookout Trail for 0.1 miles and come to the Mary's Rock Vista. There is a fun rock scramble from here to the summit.
To return, retrace your steps back along the AT and down the Meadow Spring Trail to the Hazel Mountain parking area on Skyline Drive.
To continue turn left just below the parking lot onto blue blazed Buck Hollow Trail. The Buck Hollow Trail descends the valley crossing the stream several times.
At the intersection of Buck Ridge trail, turn left on the Buck Hollow Trail and arrive back at US211 and the parking area in 0.2 miles.
