Singapore Changi Airport (SIN), opened on July 1, 1981, is not only Southeast Asia's main aviation hub but a tourist destination in its own right. Consistently awarded as the "Best Airport in the World," it stands out for its operational efficiency and for Jewel Changi Airport, a mixed-use complex connected to the terminals that houses the HSBC Rain Vortex, the world's tallest indoor waterfall, surrounded by a climate-controlled tropical forest.
