The Appalachian Trail, also called the A.T., is a footpath stretching more than 2,100 miles across mountaintop and ridge from Maine to Georgia. It enters and exits each end of this overlook and is recognized by white blazes painted on trees. Roughly two million steps straight ahead lead 860 miles to the trail’s southern end on Springer Mountain, Georgia, while three million steps behind lead 1,280 miles to its northern end atop Mt. Katahdin in Maine. Each year, about 150 thru-hikers pass here as they trek the entire A.T. Shenandoah National Park contains ninety-five miles of the A.T., and the trail crosses Skyline Drive 28 times. Blazes are spaced at intervals along the entire length of the A.T., and double blazes, one over the other, indicate a significant change in direction.
