From the parking area, follow Pretty Hollow Gap Road and Trail beside Palmer Creek to the Little Cataloochee junction. The approach is mostly level; the named trail then climbs steadily toward Davidson Gap. Several crossings over Little Davidson Branch interrupt the climb, and mossy stone walls mark the old Messer farmstead. The north side drops more steeply on switchbacks. On the return, you climb those switchbacks again before the final descent to Palmer Creek.
The route is native ground with loose rock and roots. After the gap it broadens into a smoother old road through the valley. Creek crossings can be awkward after rain, so give the water time to settle before choosing your steps.
