Six miles of the most technical creek kayaking in the eastern United States — the Green River Narrows has become a world-renowned destination for expert paddlers since the 1990s. A continuous sequence of Class IV–V+ drops through a narrow gorge of Piedmont granite, culminating in the famous Gorilla rapid (Class V+). The annual Green Race draws the world's fastest creek racers each November.
