The National Trails System Act of 1968 authorized creation of a national system of trails comprised of National Recreation Trails, National Scenic Trails, and National Historic Trails. While National Scenic Trails and National Historic Trails may only be designated by an act of Congress, National Recreation Trails may be designated by the Secretary of Interior or the Secretary of Agriculture to recognize exemplary trails of local and regional significance. Through designation, these trails are recognized as part of America's national system of trails.
