The 25th annual edition of the Appalachian Trail Thru-Hikers' Companion is now available for sale to help you plan your 2018 thru-hike or any other adventure on the A.T.

It includes all the latest information updated in the fall by field editors and ATC staff who scoured the trail and its environs from Georgia to Maine for the latest updates. (For instance, the A.T. grew by 0.7 mile over the last year.) One new feature: If a box is shaded in the table section, it's also further described in the text. We also added several hundred data points.

 The Companion
Every hiker needs a Companion!

OfficialThe Appalachian Trail Thru-Hikers' Companion is the only official ATC guidebook for thru-hikers, section-hikers and day-hikers on the Appalachian Trail. It contains a mountain's worth of information and data on shelters, water sources, town services and other hiker-oriented facilities along the 2,189-mile trail. The information is compiled and published every year by ALDHA volunteers -- many of them long-traveled veterans of the A.T. -- with valuable input from the staff of the Appalachian Trail Conservancy. It contains up-to-the-minute knowledge of the A.T. from current hikers and trail maintainers and provides essential information on hiker-oriented services on and near the trail.

This book is essential for planning an A.T. hike. We bought it for our daughter and had to return it because it is SO essential, someone else got her one as well. ... Order it as early in the year as you can and you will pay a lower price. It is worth EVERY CENT you have to pay if you are going to thru-hike the A.T.

-- Stephen Bothelon, posted January 2, 2017, on

It is available for sale online and at most outfitters, as well as bookstores that cater to outdoor interests. The book is edited by Robert "Sly" Sylvester with 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, as well as extensive information from the current edition of the A.T. Data Book. There are 288 pages with maps, illustrations, equipment-makers' toll-free numbers and trail town post office hours.

How to Become a Field Editor
Volunteers are the backbone of the Companion. A field editor's responsibility is to gather information about the trail, shelters, water sources, post offices, lodging, hostels, groceries, restaurants, laundry, campgrounds, doctors or hospitals, veterinarians, outfitters, other trail-related services and points of interest along the trail, with the purpose of enhancing all hikers' A.T. experience whether they're a day hiker, section hiker or thru-hiker.

We are looking for energetic field editors amenable to travel a section of trail and update the current information, verify hours of operation, note any changes in rates, and add any new information for inclusion in the next edition. A field editor's visit creates good relations with the communities adjacent to the trail.

Are you someone who is willing to go the extra mile? The Companion can always use your help. If you are interested in becoming a volunteer field editor or are willing to assist with the next edition of the Companion, please contact the editor, Robert "Sly" Sylvester, at

The new edition of the Companion

It was during the summer of 1993 when then-ALDHA Coordinator Frank Logue asked fellow Georgia residents Joe and Monica Cook to oversee the compilation of a new guide for A.T. hikers. It would be called the Appalachian Trail Companion and it would be made up of reports from a slew of volunteer field editors who lived up and down the general A.T. corridor.

The Appalachian Trail Conference (now the Conservancy) had been publishing a guidebook for A.T. hikers since The Philosopher's Guide by Darrell Maret in the early 1980s. It continued publishing a guide when Darrell handed over editorship to Dan Bruce. In 1993, "Wingfoot" decided to publish a guidebook on his own, so ATC cast about for a new editor to continue its publishing tradition.

Enter Frank Logue.

The ALDHA coordinator had just been chosen for a new at-large seat on ATC's Board of Managers in the summer of 1993, so the folks at ATC asked him if the members of ALDHA would be interested in taking on editorship of a guidebook for thru-hikers.

He didn't have to be asked twice, and so the first Companion was created with the help of 16 field editors. The name has since been expanded (it's now the Appalachian Trail Thru- Hikers' Companion), and the format has changed (from a tall, spiral-bound booklet to its present shape, able to fit in a quart-size plastic baggie), and it has had an impressive run of editors (three of whom went on to become ALDHA coordinators).

The book continues to prosper under current editor Robert "Sly" Sylvester and has proven to be a solid confirmation of the evolving partnership between the ATC and ALDHA.

It's the only official guidebook for thru-hikes of the Appalachian Trail.
