If it were not for the beauty of its orange and red walls and deep, snaking crannies, the Grand Canyon might be known solely as a whitewater rafting destination. As it is, whitewater rafting takes a backseat to general sightseeing, but is still an extremely popular activity within Grand Canyon National Park. Rafting provides thrills of Class IV to V rapids and a rare look inside the vast canyon. Types of Trips The National Park Service designates several types of Grand Canyon rafting trips: one day commercial trips; two- to five-day commercial trips; three- to 18-day commercial trips and self-guided trips. Commercial trips are offered by more than a dozen licensed tour companies in Arizona, Nevada, Utah and other areas.
