About This Route
The McAfee Knob to Johns Creek Valley section in Virginia's Jefferson National Forest covers 22 miles of iconic Appalachian Trail, famous for the overhanging cliff vista at McAfee Knob, one of the AT's most photographed spots. From VA-620 parking, ascend past Catawba Shelter, skirt Tinker Cliffs, and descend through McAfee Knob Shelter to Johns Creek at VA-42. This intermediate backpacking route features exposed ledges, wild ponies in nearby fields, and spring wildflowers. NPS data shows high traffic, so camp 200 feet from water per Leave No Trace. Crowds peak weekends; permits not required but check Jefferson NF fire restrictions.
Safety Considerations
Edge exposure at McAfee Knob and Tinker Cliffs demands focus; no railing, so leash dogs and avoid selfies near drop-offs. Heat exhaustion hits summer; hydrate proactively with electrolytes from Nuun tablets. Black bears less common than south, but hang food. Lyme disease from ticks; DEET 30% repellent essential. Lightning-prone balds; REI protocol: seek low ground if thunder within 30 minutes. Poor cell service beyond Catawba; carry SPOT Gen4 messenger. ATC advises sharing plans, avoiding strangers at road crossings like VA-311, and mental prep for fatigue on 1,000-foot climbs. Watch for copperheads near streams.
