The word "grand" doesn't even come close to describing this canyon. This gigantic gap in northern Arizona is certainly a natural wonder, measuring over 277 river miles in length, up to 18 miles in breadth, and a mile deep. People have gone from all over the world for ages to gaze out over its scarlet and orange splendor. This is the location to go if you want to go camping in the woods or go trekking in the mountains.
