Since I moved to Georgia 5 years ago, this book has been my most reliable hiking companion. The maps and directions are good, and the trail descriptions are detailed. A handy sidebar tells you the important stuff: what towns the trail is near, what features you'll encounter, the difficulty rating, the ranger district, and the length. Trail histories and Cherokee name translations add interest to the excitement of hiking in the lush Appalachians.
The "highlights" sections for each trail are especially nice -- peaks, falls, rapids, creeks, scenic views, notable ruins, giant trees, etc. are listed along with the mileage. It also has a decent amount of room for your own notes.
I wouldn't mind if they had a new edition with more Georgia trails; I know some of the newer volumes in this series feature more Georgia trails. However, I realize a more complete guide might have to be about 900 pages and therefore difficult to fit in the Camelback. It's a good book, though, and I've recommended it to many.
