Appalachian Trail thru-hikers' companion

the long version

"The champion of Appalachian Trail guides for thru-hiking for 25 years! 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, doing the 2,189.8 miles in pieces instead of all at once."
