It is a steady climb of around 1700' in about 4.4 miles to the Knob from the VA311 parking area so you will get a good workout. On a clear day you will have some of the best views in the Southern Shenandoah Valley. Due to its popularity you will not be alone on this hike, but the overhang of McAfee Knob and its views make up for the lack of solitude. From the right side of the A.T. parking area, cross over VA311 and pick up the white blazed A.T. north. In about 0.3 miles there will be an information kiosk on the left. Continue on the A.T. crossing four wooden walkways prior to reaching the Johns Spring Shelter on the right in 0.8 miles. There will be another five wooden walkways before reaching the Catawba Mountain Shelter in 1.4 miles. In less than 0.1 miles before the shelter on the left, you will notice a spring with a white pipe protruding from some rocks with a constant stream of water (note: always treat water from unknown sources). Staying on the A.T. for another 0.1 miles arrive at two good camp sites, the A.T. bears to the left just before the camp sites. McAfee Knob is one of the most photographed spots on the Appalachian Trail (A.T.) as it winds its way through Virginia. Roanoke.com states: "In Virginia, McAfee Knob is the Appalachian Trail's poster and postcard image. Pick up an Appalachian Trail calendar and there's a good chance it's there." The Knob has an almost 270 degree panorama of the Catawba Valley and North Mountain to the West, Tinker Cliffs to the North and the Roanoke Valley to the East. If you are going to do this as a backpack and plan on camping at the Pig Farm campsite or Campbell Shelter the total distance will be 9.5 miles.
