Trail Notes: From the parking area, follow yellow-blazed Scothorn Gap Trail. Soon cross Passage Creek. Ascend steeply up an old forest road and then more gradually as the trail continues more obliquely up the side of the mountain.

At about 0.7 miles the old forest road will bear to the left. Continue straight, following the yellow blazes.

At about 1 mile, pass a beaver pond on the left and come to the intersection with orange-blazed Massanutten trail straight ahead (your return route) and to the right. Yellow-blazed Scothorn Gap trail turns left. Turn left staying on Scothorn Gap Trail.

At 1.6 miles from the last intersection arrive at the intersection with blue-blazed Gap Creek Trail. (This trail's western terminus is also on the forest road you parked on and can be used as a quicker up and back route to Duncan Knob.) Turn right and climb rapidly for 0.3 miles to the Peach Orchard, a flat area great for camping although it is dry. The nearest water sources are Passage Creek and Gap Creek that runs through Duncan Hollow at the eastern base of the ridge.

At the Peach Orchard turn left onto the white-blazed Duncan Knob Spur Trail. At times the blazes are painted on the rocks. In 0.2 miles arrive at the focal point of the hike. The talus rock at the base of the knob is a great lunch spot. A greater spot is at the top of the 200 foot tall rock pile in front of you. I would recommend leaving your pack and tacking your camera and water to the top. You might need your hands for the climb.

Following the blazes back to the Peach Orchard is harder than going out to the knob. Just stay close to the edge of forest and rocks on your right side to regain the trail.

Turn left onto the continuation of Gap Creek Trail, descending steeply into Duncan Hollow. At about 0.7 miles from the previous intersection meet the orange-blazed Massanutten Trail and Gap Creek. If you are backpacking there are a couple of good campsites complete with a fire pit and stone furniture just on the other side of the creek.
