Terrapin Adventures never fails to live up to its name—even their swing set gets the stomach fluttering with excitement. To be fair, though, the swing in question is anything but the traditional apparatus you'd find at a city park. It seats three people and starts its trajectory 40 feet above the ground, generating 2 Gs of adrenaline as it swishes riders back and forth over the landscape. The park's other attractions are equally exhilarating. On the high ropes course, visitors attached to sturdy safety harnesses cross 18 traverses situated between lofty platforms; some must be tackled via a rickety bridge, while others require leaps of faith. The 43-foot high climbing tower offers 10 routes up and down, including a head-first downward climb over the Rainbow Serpent. Otherwise, the 330-foot-long zipline sends visitors gliding through the treetops at speeds of up to 20 mph, fast enough to beat the USA track team's star squirrel.
