Fodor's Expert Review Knife Edge Trail

Perfect for a sunset stroll, this easy 2-mile (round-trip) walk around the north rim of the park leads to an overlook of the Montezuma Valley. If you stop at all the flora identification points that the trail pamphlet suggests, the hike takes about 1½ to 2 hours. The patches of asphalt you spot along the way are leftovers from old Knife Edge Road, built in 1914 as the main entryway into the park. Easy.
