Historic Banning Mills, Georgia
According to the 2012 Guinness Book of World Records, the wooden climbing tower at Historic Banning Mills in rural North Georgia is the tallest free-standing climbing wall in the world at over 140 feet (Reno BaseCamp is taller, but was constructed on the side of an already-standing building). A number of overhangs, traverses and other features mean that this tower can challenge even the most skilled climbers. Banning claims to have a route classed as 5.12, one of the most difficult grades in the climbing world. The tower is certainly a headline-stealer, but this adventure destination has other attractions as well. Banning has one of the world's longest zip-line tours. Kayaking, an aerial challenge park, horseback riding and even falconry experiences are also part of the offerings.
