I'm looking for a good twenty to forty mile loop trail (or a longer one with side trails that can be turned into a twenty to forty mile loop), with good elevation change (between 500 ft and 2,000 ft of change along the trail) within four hours' drive of Gainesville, FL. Plentiful water stops would be preferred even over a shorter drive, assuming that the above requirements are met.
I don't know if such a thing exists, but I'd like to get a good weekend in backpacking and this seems a good place to ask.
As an example for distances from Gainesville: Atlanta is about five hours' drive, while Savannah is about three and an half. Mongomery is about six hours, Columbus about five.
Please feel free to direct me to wherever you might want; more information on the areas recommended is always a good thing!
