4. The Knife Edge, Katahdin, Baxter State Park
This is another trail with a name that’s fairly indicative of what to expect. At the end of the 2,160-mile Appalachian Trail hikers will ascend Katahdin’s western face. But, those with hearty souls can tackle the east face. This completely exposed ridge is significantly more dangerous, best for expert hikers. But, if you can manage it, the views are a stunning way to end the AT hike.
