Reaching Jewel Changi Airport from Terminal 1 (T1) is the simplest transition in the entire airport complex because the two buildings are physically integrated. In 2026, you simply need to head to the Level 2 Arrivals Hall of T1. From there, you will see clear, illuminated signage for "Jewel." You walk through a seamless link bridge that deposits you directly into the North Gateway of Jewel. The walk takes less than two to three minutes. This proximity makes T1 the "premier" terminal for those wanting immediate access to the HSBC Rain Vortex and the Shiseido Forest Valley. If you are arriving from a flight, you must clear immigration and collect your luggage first, as Jewel is located in the public "landside" area of the airport. For transit passengers in 2026 who do not wish to clear immigration, you can catch the Skytrain that runs between T2 and T3; it actually passes directly through the Jewel complex, offering a spectacular view of the waterfall, though you cannot exit the train inside Jewel without passing through passport control.
