National Recreation Areas (NRAs) are designated lands managed by the federal government to provide outdoor recreational opportunities while protecting natural and cultural resources. These areas often include lakes, rivers, forests, and trails, making them ideal for activities like hiking, camping, fishing, and boating. NRAs aim to balance recreation with conservation, ensuring that visitors can enjoy nature while preserving the environment for future generations. Examples of NRAs include the Lake Mead National Recreation Area and the Santa Monica Mountains National Recreation Area, which offer diverse landscapes and recreational activities for people of all ages.
