Royal Caribbean revealed the images of long time anticipated slide named "The Ultimate Abyss" the highest slide of the sea, able to intimidate the most courageous and daring and test their courage aboard the Harmony of the Seas setting sail in spring of 2016.

Two Abyss slides will tower at 150 feet (46 meters) above sea level and will be located at the aft of the ship overlooking the Aqua Theater. The pair of side-by-side custom-built slides will see adrenalin-seeking travelers hurtle along a chilling 30 meters (100 foot) drop that includes serpentine-like twists and turns. People who dare to take this ride will experience speed of nine miles per hour sliding from Deck 16 to Deck 6.
