In Short
Final destination of the Appalachian Trail, Mount Katahdin is nearly one mile high at 5,267 feet, but you might as well be five miles up for all the views this solitary massif affords.The most dramatic route connects the mountain's two peaks with the Knife Edge, an aptly named ridge that's not for those with a fear of heights. Only those in excellent shape should attempt it. And keep a watchful eye for threatening weather when above the tree line.
