There are lots of free things to see and do across Changi Airport's terminals. Create your own mini museum walk around the art installations, enjoy the sights at the Viewing Malls, or relax in the lush mini gardens and green spaces to take a break from the hustle and bustle of the world.

Singapore Changi Airport offers a unique mix of free and paid attractions, making it a "lifestyle destination" as much as a transit hub. The most iconic attraction, the HSBC Rain Vortex (the world's tallest indoor waterfall) and the surrounding Shiseido Forest Valley, are completely free to visit for both travelers and the general public. Additionally, the airport provides free 24-hour movie theaters in Terminals 2 and 3, and themed gardens like the Butterfly Garden and Sunflower Garden are complimentary for transit passengers. However, many of the more "active" attractions located in the Jewel's Canopy Park require a paid ticket. These include the Manulife Sky Nets, the Hedge Maze, and the Canopy Bridge. As of 2026, while you can spend an entire layover enjoying the "Arrival Garden" and world-class art installations without spending a cent, those wanting to experience the high-thrill architectural features or the "Changi Experience Studio" interactive museum should expect to pay between $15 and $55 SGD depending on the bundle selected.
