The epic journey of the 2,180 mile national scenic trail
It runs through 14 states, from Maine to Georgia, and it is one of the longest continuously marked footpaths in the world at about 2,180 miles. It is the Appalachian Trail - a tribute to nature that took more than 15 years and countless arguments to complete. In Appalachian Trail, previously seen on public television, meet the people behind the trail, including the man who came up with the idea in 1921 - Benton MacKaye and the man who, in the end, made it happen Myron Avery.
Plus, hear from some of the trails most famous hikers: Earl Shaffer, a World War II veteran, was the first person to thru-hike the entire distance of the trail in 1948. He would go on to complete the trail two more times, completing the final hike just two weeks before his 80th birthday. And Bill Irwin is the only blind hiker to have completed the Appalachian Trail, which he did with his seeing eye dog, Orient.
