The Appalachian Trail Data Book, updated every fall after each year's work by dedicated volunteers on this legendary footpath, is an essential companion for the Appalachian Trail hiker- whether out for the day or a six-month thru-hike from Georgia to Maine or Maine to Georgia. (It consistently ranks No. 1 among the publications long-distance hikers take with them.) It condenses into state-by-state tables-in an at-a-glance format-the distance information detailed in the 11 official Appalachian Trail guidebooks. The tables include coded information on shelter locations, water sources, post offices, road crossings, supply sources, lodging, and eateries. Distances between major features and facilities are presented for both north-to-south and south-to-north travelers, following the white blazes of the A.T.
