This is a new trail as of Spring 2012. The park officials have closed the Summit Trail beyond the split to this Chestnut Oak Trail, and prohibit visitors from accessing the communications towers at the end of the road. Chestnut Oak runs basically east and west from the Overlook/Summit Trails to the western loop of the Occoneechee Mtn Loop Trail, along the higher ridge line. It runs through some nice Mountain Laurel, and Witch Hazel patches along the way.
Most people combine the Occoneechee Mountain Loop Trail with the Summit and Overlook Trails as one longer hike. The new Chestnut Oak Trail now links the Summit Trail with the west side of the park on the higher ridge line.
