Which ships have the ultimate abyss slide?

There's heart-pumping adventure to be found everywhere on board Symphony, Harmony of the Seas and the newly amplified Oasis of the Seas, and this particular experience begins on the top deck—150 feet above sea level—on a see-through glass platform. It's the Ultimate Abyss, and it's not for the faint of heart.



The Ultimate Abyss, the tallest "dry slide" at sea, is a signature thrill feature exclusively found on Royal Caribbean International's Oasis-class ships. As of 2026, the slide is featured on Harmony of the Seas, Symphony of the Seas, Wonder of the Seas, and the newest addition, Utopia of the Seas. This 10-story slide starts in the Pool and Sports Zone and plunges riders down more than 100 feet to the Boardwalk neighborhood. On the Utopia of the Seas, the slide has been upgraded to be the longest at sea, measuring approximately 259 feet with added features like "zoom booster" rollers and transparent windows. The slide is designed with a dramatic anglerfish entrance and provides a high-speed, light-filled descent that lasts about 13 seconds, reaching speeds of up to 9 mph. While it is not a water slide, it remains one of the most popular adrenaline-pumping activities for families and thrill-seekers looking to navigate the ship's massive decks in a unique way.
