We bought a GA Backpacker Guide book a couple of years ago and it is very helpful. It helps up pick places that will fit our schedule for that weekend. It is nice to have a lay of the land and tips on parking before you drive out to a new place.
I'm down in Augusta and we don't have much backpacking around here but I love gettin out in the good ol out doors so I might have to make a trip up there!
Love hitting the southern tip of the AT. We go to Amicalola often and hike the approach trail. Very nice. If you haven't seen Amicalola Falls, you're missing out.
The Georgia section of the Appalachian Trail is a hard yet fun trail to hike. So far I've done most of the Georgia section as well as up into the N.C. and Tenn. area too. It's a well used trail that can have some good views along the way.
another good hike is right by Panther Creek. If you go past the Sandy Bottoms camp grounds for 4-5 miles you will see a primitive camp site on the left. It is pretty hard to miss, it cuts off to the left and has a good parking area. If you cross the river, there is an old logging trail that winds up the mountain. It's a good hike and you get some great views from the top.
