Thru-Hikers' Companion

Every fall or early winter, a new edition of the A.T. Thru-Hikers' Companion—one of Appalachian Trail Conservancy's best-selling books—is published to update hikers on changes in mileages and facilities after the summer work and relocation season. Current editions can be ordered from the  Ultimate A.T. Store or by calling 1-888-AT STORE (888-287-8673)

The Appalachian Trail Thru-Hikers’ Companion, a collaboration between the Appalachian Long Distance Hikers Association (ALDHA) and ATC, takes a south-to-north perspective of the Trail and details extensive information (and maps) on town services along the Trail. It also has advice on getting to (and from) the termini and some basic reference material (post-office list, mileages, elevation, etc.). While the point of view of the Companion is that of thru-hikers, this book has proven over more than 15 years its value to section-hikers as well.

Another favorite, the Appalachian Trail Data Book, is a compilation of less than 100 pages of distances between major landmarks drawn from all 11 official A.T. guides. It is a favorite among section hikers to track their distances and, because it is updated every year, it is a useful tool to verify map information. Resembling a 20th-century railroad timetable with cumulative mileages on either side of the page, it has a north-to-south orientation. It is an essential aid in planning A.T. trips and is the source each December for the new official mileage of the Trail. Current editions can be ordered from the Ultimate A.T. Store or by calling 1-888-AT STORE (888-287-8673)
