"Rappelling down waterfalls isn’t for the faint of heart, but it's an unforgettable thrill for those who can bear it. Rappel Maui operates out of a 30-acre botanical garden off the famous Hana Highway , where you're given pro-level equipment (footwear, harnesses, backpacks with dry kegs, flotation jackets, and helmets) and plenty of instruction before you're encouraged to practice on a dry rainforest wall. Once you've summoned the confidence—and perhaps the courage—you rappel down waterfalls and into natural pools. Keep in mind: This is a physically demanding tour, with a half-mile of hiking as well as some swimming, and children must be 10 and older and weigh at least 70 pounds." - Juliana Shallcross
