Cataloochee Divide Trail follows the crest and park boundary from Cove Creek Gap to Double Gap, where it meets Hemphill Bald Trail. The mapped corridor is about 6.3 miles one way, climbing from roughly 4,200 feet to just over 5,000 feet. Allow four to five hours in this direction. A true through-hike needs a pickup at Double Gap; public parking there was not confirmed. Without a shuttle, the well-described day hike turns around at Purchase Knob and returns the same way, about 9 miles round trip. Distance records disagree: a separate trail-length figure says 8.7 miles, while the connected mapped line measures 6.3, so treat the line-based distance as an estimate.
