In 1968, Congress established the National Trails System and designated the first two national trails - the Appalachian and Pacific Crest National Scenic Trails. Over the past 40 years, Congress has added six more National Scenic and 17 National Historic Trails.

The National Trail System spans more than 50,000 miles across 47 states. Thirteen of these trails, and more than 5,100 trail miles, are managed by the BLM’s Conservation System, including premier hiking and backpacking trails such as the Pacific Crest and Continental Divide National Scenic Trails, and the culturally significant Lewis and Clark and Iditarod National Historic Trails.

According to the BLM, which cooperates with other federal agencies to manage the National Trails System, "National Historic Trails are extended trails that closely follow a historic trail or route of travel of national significance. Designation identifies and protects historic routes, historic remnants, and artifacts for public use and enjoyment." The BLM manages more than 4,500 miles of 10 National Historic Trails.

National Scenic Trails are "extended trails that provide maximum outdoor recreation potential and for the conservation and enjoyment of the various qualities – scenic, historical, natural, and cultural – of the areas they pass through." The BLM manages more than 600 miles of the Continental Divide, Pacific Crest and Potomac Heritage National Scenic Trails.

These trails help boost the economy of small communities, showcase the grandeur of our western landscapes, and provide us an opportunity to travel our country's historic journeys.
