National Scenic and Recreational Rivers are designated waterways in the United States that offer exceptional natural beauty and recreational opportunities. These rivers are protected under the National Wild and Scenic Rivers Act, which aims to preserve their free-flowing condition and enhance their scenic, recreational, and ecological values. The designation helps to maintain the rivers' health and surrounding landscapes, allowing for activities like canoeing, fishing, and hiking. By protecting these areas, the government ensures that future generations can enjoy the unique experiences and natural wonders these rivers provide.
