For 2020, the length of the Appalachian Trail from Maine to Georgia (or vice versa) is officially 2,193.0 miles, as documented in this classic work.

Sometimes termed "the bible of A.T. hiking" because of its use in essential hike planning, each year's Data Book consolidates the most basic information from 11 detailed official guidebooks into a lightweight table of distances between major Appalachian Trail shelters, road-crossings, and features. It is divided according to the guidebook volumes and updated each December to account for Trail relocations, new (or removed) shelters, and other changes. In addition to codes for lodging, food, water, and other essentials, the Data Book is keyed to both the individual guidebook sections and to the separate maps.

Compiled since 1983 by Daniel D. Chazin of Teaneck, N.J., a volunteer with the N.Y.-N.J. Trail Conference. Forty-second Edition, 2019.

    Used on my three day AT hike. Accurate and helpful to help plan my trip. Shelters/campsites and water access was helpful to have.

  3. Former thru hiker 5 Star Review

    I have owned countless Data Books and they never disappoint.

  4. Decent. Not Great 3 Star Review

    (Submitted on Mar 16th 2020)

    The guide goes from the North to the South instead of NOBU I guess I didn't read the fine print so I have to go from the back of the book to the front . I think it gives all the Gaps and Shelter locations but that is pretty much all it does .

  5. Must Have 5 Star Review

    (Submitted on Jan 21st 2020)

    I had no real idea of distances and the whereabouts of some sleeping arrangements. This will be a very useful tool for my hike and maybe for others if I can help.
