A National Recreation Area (NRA) is a protected area in the United States designated for outdoor recreation and conservation. These areas are managed by the National Park Service and provide opportunities for activities such as hiking, camping, fishing, and boating. NRAs aim to balance recreational use with the preservation of natural and cultural resources. National Recreation Areas often feature scenic landscapes, wildlife habitats, and historical sites. They serve as important spaces for public enjoyment and education, promoting awareness of the environment. Examples of NRAs include the Lake Mead National Recreation Area and the Santa Monica Mountains National Recreation Area.
