With Maui’s only rappelling outfitter, you can descend waterfalls and jungle walls into a secluded, privately owned rain-forest canyon featured in the opening scenes of Jurassic Park. The Classic Tour tackles 30- and 50-foot waterfalls with short swims at the bottom, while the eight-hour Extended Tour kicks things up a notch with rappelling off cliffs, zipping through free space, and rock climbing up the face of waterfalls. Both experiences include gear, a picnic lunch, and—crucially—transport to the rain forest reserve, so you don’t have to worry about navigating the winding Hana Highway by yourself.
