A National Scenic Riverway is a designated area in the United States that highlights the natural beauty and recreational opportunities of specific rivers. These riverways are protected to preserve their scenic, cultural, and ecological values, allowing for activities like fishing, canoeing, and hiking along their banks. The designation is part of the National Wild and Scenic Rivers System, established by the Wild and Scenic Rivers Act of 1968. This program aims to safeguard rivers that possess outstanding natural, cultural, and recreational significance, ensuring they remain unspoiled for future generations.
