99 days of Harmony: Ultimate Abyss

14 Feb 2016

We're counting down the days until Royal Caribbean's Harmony of the Seas debuts, with our 99 days of Quantum countdown.  Each day we will post something about this amazing new ship.

Ultimate Abyss

Guests onboard Harmony of the Seas can look forward to a brand new thrill: a story drop on a brand new slide called, "Ultimate Abyss."

Ultimate Abyss will be the tallest slide at sea and also an epic adventure.


The Ultimate Abyss is more than 150 feet above sea level and offers side-by-side slides that send guests down 10 decks at a rate of 9 miles per hour.

Launching onto the ride from a glass platform, guests can take one last look at the Boardwalk 10 decks below before climbing onto a customized mat and taking the plunge into the depths of the daunting slides. Spontaneous audio effects within each tunnel create a multi-sensory thrill for daring guests willing to test their mettle while traversing 216 feet through the one-of-a-kind slide duo. The Ultimate Abyss is made up of two separate cylinders, a reflection of one-another, each with a diameter of approximately 2.6 feet and constructed of stainless steel.

Stay tuned for tomorrow's post, as we celebrate 99 days of Harmony!
