Yes, Oasis of the Seas features a signature zipline that is one of the most popular high-adrenaline activities on the ship. Suspended nine decks above the Boardwalk neighborhood, the zipline allows guests to soar 82 feet across the open-air center of the ship. This experience is entirely complimentary (included in your cruise fare) and typically operates on a first-come, first-served basis without the need for advance reservations. Riders must meet specific safety requirements, including a minimum height of 52 inches and a weight between 75 and 275 pounds. In 2026, it remains a "must-do" for thrill-seekers, offering a unique perspective of the AquaTheater and the ocean beyond. It is recommended to visit early in the cruise or during port days to avoid the longest queues. Be sure to bring socks and closed-toe shoes, as they are mandatory for participation.
