"U.S. National Whitewater Center is the largest man-made whitewater river in the world, and it's also an Olympic training site. But there's so much more than rapids here; rather, it's a 1,300-acre playground for the entire family. With rock climbing and mountain biking on more than 50 miles of trails, the complex feels like an Outside magazine spread—right outside Charlotte. What you do here depends on your interests. If you're a river rat, you'll love the whitewater rapids; if heights are your thing, try the zip lines and rock climbing." - Nancy DePalma
