I was all excited to hike the Appalachian trail. I realized later that the trail does go through Pennsylvania, the nearest point is like an hour to the north of Bethlehem, so I didn’t need to make the 10 hour drive down to Tennessee to hike it. But I think this stretch of the trail is almost the highest point along the whole Appalachian trail. The highest point is Clingmans Dome (6643 feet or 2025m).
