Yes, Harmony of the Seas features a massive water slide complex known as "The Perfect Storm." This trio of high-speed slides—named Typhoon, Cyclone, and Supercell—provides guests with multi-story twists and turns high above the ship's Central Park neighborhood. Supercell is particularly unique as it features a large "champagne bowl" that swirls riders around before dropping them into the final flume. In addition to these water slides, the ship is famous for The Ultimate Abyss, which is a dry slide that plunges 10 stories down from the Sports Deck to the Boardwalk; while it doesn't use water, it is one of the tallest and most exhilarating slides at sea. For younger guests, the Splashaway Bay water park also includes smaller, kid-friendly slides. As of its 2026 "Amplification" updates, these features remain flagship attractions for families seeking thrills alongside the ship's four pools and ten whirlpools.
