The most widely used [citation needed] grading system is the International Scale of River Difficulty, where whitewater (either an individual rapid, or the entire river) is classed in six categories from class I (the easiest and safest) to class VI (the most difficult and most dangerous).

Multi-day rafting trips by do-it-yourself rafters and commercial rafting companies through the National Wild and Scenic Rivers System have the potential to develop environmental stewardship and general environmental behavior. Studies suggest that environmental efficacy increases when there is an increase in the length of the trip, daily ...
