Pick,
Welcome to Foottrails.
Depending on where you live I would suggest hiking the Appalachain Trail north or south. I would recommend starting at Amicalola Falls Lodge to Unicoi Gap. 35-40 miles. This is a great hike. Another note, there will be several thru-hikers on the trail heading to Maine in the spring. Tim Homan,a local author has several books about hiking trails
in the Southeast.
If you don't have this book you need to pick it up.
"Hiking Trails of North Georgia by Tim Homan".

Happy Trails,
