The longest tube water slide resides in Malaysia. It's simply called “The Longest” and traipses down a canopied mountain inside the Escape Penang amusement park. The slide is 3,645 feet, or the equivalent of 12 football fields, and dwarfs all other water slides in terms of length.

As of 2026, the record for the world's longest permanent water slide is held by "The Longest" at ESCAPE Theme Park in Penang, Malaysia, which measures an incredible 3,645 feet (1,111 meters). Riders spend roughly four minutes sliding through the natural jungle canopy on a winding yellow tube. In the category of "water coasters" (rides that use magnets or water jets to go uphill), the Mammoth at Holiday World in Indiana was the long-standing record holder at 1,763 feet, but it has been challenged by newer installations. In 2026, Six Flags Over Texas introduced the Tormenta Rampaging Run, which, while classified as a "Giga Dive Coaster," includes record-breaking water-themed segments. For traditional log flumes, the Chiapas ride at Phantasialand in Germany is often cited for its length and technical complexity, though it is the Malaysian jungle slide that holds the Guinness World Record for pure distance. These massive rides use advanced water-recycling systems to pump thousands of gallons per minute to maintain the flow over such vast distances.
