National Parkways are scenic roads designed to provide access to and enhance the natural beauty of national parks and surrounding areas. They often feature picturesque views, recreational opportunities, and historical landmarks, making them popular for leisurely drives and outdoor activities. These parkways are typically maintained by the National Park Service and are intended to preserve the landscape while promoting tourism. Examples include the Blue Ridge Parkway and the Natchez Trace Parkway, both of which offer unique experiences and showcase the diverse ecosystems and cultural heritage of the regions they traverse.
