Mount Chapman is approximately from the nearest parking lot at the Cosby Campground and from Newfound Gap. From the Cosby Campground (specifically behind Campsite B51), the Snake Den Ridge Trail winds for to its junction with the Appalachian Trail at Inadu Knob. Following the AT from Inadu, Chapman's main peak is approximately to the south, with the trail first crossing the slopes of Old Black, Mount Guyot, and Tricorner Knob. A short bushwhack is required to reach the summit.
