- Essential for basic planning of any A.T. hike
- Culled from all 11 A.T. guidebooks
- Reflects all major changes from the previous 12 months
Sometimes termed "the bible of A.T. hiking" because of its use in
essential hike planning, each year's Data Book consolidates the basic
information from the 11 official ATC guidebooks into a lightweight table
of distances between major A.T. shelters, road-crossings, and features.
Divided to align with the guidebook volumes, the Data Book is updated
each December to address trail relocations, new or removed shelters, and
other changes. In addition to including codes for lodging, food, water,
and other essentials, the Data Book is keyed to both the individual
guidebook sections and the separate maps.
