The champion of Appalachian Trail guides for thru-hiking for two decades! With professionally crafted elevation profiles, almost 50 updated maps, and redesigned tables for more at-a-glance information on-trail.

Still the only such guide written by volunteers for which all the proceeds are returned to the Trail by these two nonprofits!

The Appalachian Trail Conservancy and the Appalachian Long Distance Hikers Association collaborate each year on a guide especially designed for potential thru-hikers who want the basic information for a five- to six-month trek in the woods, at a reasonable price, but also want the adventure of finding out the extras for themselves. A favorite of section-hikers, too.

With fact-checking research by more than three dozen thru-hiker volunteers in 14 states, backed by the first-hand information of the trail's volunteer and staff maintainers and managers and extensive information from the 2016 A.T. Data Book. Equipment-makers' toll-free numbers, post office hours, much more included.

ALDHA is an organization of past, present and future hikers of the Appalachian Trail.  It was formed in 1981 by previous thru-hikers of the Appalachian Trail but soon become a "users groups" for backpackers and hikers of all the U.S. scenic trails and most major hiking paths abroad.
