How fast is the ultimate abyss?

So how fast can you go down a slide? Well, the Ultimate Abyss will have you speeding down at 9 miles per hour!



The Ultimate Abyss, found on Royal Caribbean's Oasis-class ships (including the record-breaking Utopia of the Seas in 2026), is the tallest "dry slide" at sea. It is designed for thrill rather than pure terminal velocity, with riders reaching top speeds of approximately 9 miles per hour (14.5 km/h). While 9 mph sounds modest on paper, the experience feels significantly faster because you are sliding in total darkness through a translucent PVC tube that twists and turns over a 100-foot (30-meter) drop. The journey takes about 13 to 19 seconds to descend 10 decks, from Deck 16 down to the Boardwalk on Deck 6. Riders sit on custom mats to reduce friction and protect their skin, which enhances the sensation of speed. The attraction uses integrated "multisensory" effects, including haptic pings and eerie audio, to psychologically amplify the rush as you spiral toward the AquaTheater at the aft of the ship, making it one of the most intense non-water attractions in the cruise industry.
