Adventure-seekers in Maui should look no further than Kapalua Ziplines. This course has over seven lines that reach speeds up to 60 miles per hour. Two of the lines are over 2,000 feet long! It’s also home to the longest suspension bridge in Hawaii! During whale watching season, the team at Kapalua have been known to spot whales off in the distance. It’s a must-do Maui experience.
