Includes national scenic trails (the Appalachian Trail, the Pacific Crest Trail, and the Continental Divide Trail), national historic trails, national recreation trails, and national water trails, together with a category for potential trails to be studied.

American Trails works to encourage designation and stewardship of all kinds of trails—hiking trails, biking trails, mountain biking trails, cross-country ski trails, and trails open to off-road vehicles, motorcycles, and snowmobiles.
