The Ultimate Abyss
Having first appeared on Harmony of the Seas in 2016—followed by Symphony of the Seas in 2018—Royal Caribbean’s boldest thrill, The Ultimate Abyss, will have hearts racing as adventure seekers twist and turn their way down 216 feet in the serpentine-like slide, the tallest at sea. The ten-story slide, the tallest at sea, takes guests from the Pool and Sports Zone on deck 16 to the Boardwalk on deck 6 in 13 seconds flat. We dare you to find a faster commute!
