Zoom down the longest zip line in the world.
Labadee, Haiti is home to not only a private beach, but also the world’s longest zip line over water. At 2,600 feet long and 500 feet high, the Dragon’s Breath Flight Line is not for the faint of heart. After, you can reward yourself with a relaxing paddle through the Bay of Labadee and see what it looks like from sea level. If you don’t feel like leaving the ship that day, though, you can zip line from bow to stern on Harmony of the Seas too. The zip line on the ship is 10 decks up, and you'll win all the bragging rights if you tackle it.
