The Grand Canyon Of Yellowstone is the most breathtaking sight inside Yellowstone Park. Twenty miles long, the canyon is up to 4,000-feet wide and 1,200-feet deep in places. From several vantage points, you can view Lower Falls plunging steeply into the canyon 308 feet, or the Upper Falls tumbling 109 feet.
