Mount Katahdin, at Baxter State Park in Maine, is a fitting end to the Appalachian Trail in the north. Reaching the mass of rock atop the 5,267 foot summit is a challenge to the most experienced climber, even the AT thru-hiker who spent the last six months racking up more than 2,100 miles. Yet, it’s somewhat of a disappointment that the AT ascends Katahdin from the Hunt Trail, the easiest (if there’s such a thing) and least spectacular path to the peak. For an unparalleled mountainous ascent in the northeast, you should opt for the Knife Edge. Like the name implies, this three to foot wide granite sidewalk sharply drops off more than 1,500 feet on either side.
