Xtreme Adventures, Brewer

From a distance, Xtreme Adventures might look like a giant playground. But that's not all it is. Its aerial adventure course also serves as a fast-track education in teamwork for its visitors, who include families, groups of friends or coworkers, and dysfunctional ant colonies. Safety-minded staff instruct guests ages 4 and older in the basics of the ropes course, but after that it's up to each climber to rely on a buddy to scramble across tightropes, cargo nets, and hanging vines, all suspended up to 35 feet off the ground to ensure safety from wandering giraffes.

The giant swing and four ziplines—some of them four stories high—offer a different kind of rush. The swing sets hearts pumping with a 35-foot drop, and the ziplines send guests soaring through the treetops on guided flights up to 600 feet long.
