Jewel Rain Vortex
Daily 10:00–22:00; light shows 20:00 & 21:00 (plus 22:00 Fri–Sun) · MRT Changi Airport (CG2)
Famous for: The world's tallest indoor waterfall
A 40-metre waterfall pouring through a glass doughnut next to the airport. Absurd, and free to stare at.
💡 The water runs 10:00–22:00 only. The free view from the Level 1 forest floor is the best one.
