Go on, let out a wild holler as you soar above a rainforest gulch or through a eucalyptus grove. Pioneers of this internationally popular activity, the Skyline owners brought the first ziplines to the U.S. and launched them from their home, right here on Maui. Skyline has two courses, one with ocean and island views in Kaanapali and the other in a forest halfway up Haleakala. Both are fast and fun, the guides are savvy and safety-conscious, and the scenery breathtaking. Kaanapali’s eight-line tour lasts approximately 3.5 hours and its 11-line tour about 4 hours; Haleakala’s five-line tour takes about 90 minutes. This eco-conscious company is also carbon-neutral and donates thousands of dollars to local environmental agencies. Tip: Book online to save $10 off for adults and $50 off for children 8 to 13.
