The famous indoor waterfall at Singapore Changi Airport, known as the HSBC Rain Vortex, is located in Jewel Changi Airport. Jewel is a multi-dimensional lifestyle destination that is physically connected to Terminals 1, 2, and 3. Specifically, it is directly accessible from the Arrival Hall of Terminal 1 and via pedestrian link bridges from Terminals 2 and 3. While the Rain Vortex is in Jewel (which is landside, meaning you must pass through immigration to see it up close), travelers in transit can catch a glimpse of it by taking the Skytrain that connects Terminals 2 and 3, as the track passes right through the Jewel atrium. Separately, there is a second, digital waterfall called "The Wonderfall" located inside the Departure Hall of Terminal 2. This is a 14-meter-tall LED wall that creates a mesmerizing digital cascade. So, while the "real" waterfall is in the Jewel complex, Terminal 2 offers its own high-tech digital version for passengers who remain airside.
