Yes, Jewel Changi Airport is directly connected to Terminal 3 via a pedestrian bridge on Level 2 (Departure Level). The walk takes approximately 5 to 10 minutes and is fully air-conditioned, featuring moving walkways to make the transition easier for those with luggage. Jewel is centrally located in the heart of the airport complex, acting as a hub that connects Terminals 1, 2, and 3. While Terminal 1 is the most integrated (its Arrival Hall leads directly into Jewel's North Gateway), the link from T3 is just as convenient. If you are arriving at Terminal 4, you cannot walk directly to Jewel; you must first take the complimentary airport shuttle bus to Terminal 2 and then use the link bridge there. Because Jewel is located in the public area of the airport, you must clear immigration and "enter" Singapore to see the famous HSBC Rain Vortex waterfall and Shiseido Forest Valley. This makes it an ideal destination for passengers with long layovers who want to experience a world-class lifestyle destination without leaving the airport grounds.
