Just a heads up– this loop is no walk in the park! The constant inclines and declines here are no joke (maybe 5-10% of the trail is actually level?!)! AT Thru-Hikers often include this as one of the toughest parts of the entire Appalachian Trail! Hiking Upward has the elevation gain of 3,960 feet, but I’ve read the actual change in elevation is about 7,000 feet! So I definitely recommend you be in decent shape (and bring lots of water or a water filter to fill up at the creeks!).
