Observing the way water falls from the highest of heights, and cascade over rocks could easily bring a wave of calmness, even to those among us who are the most stressed. While Singapore lacks natural waterfalls, it makes up with man-made beauties including the world’s tallest indoor waterfall: the Rain Vortex at Jewel Changi Airport. And since jetting off to a country with natural, awe-inspiring torrents like Canada for Niagara Falls and Vietnam for Ban Gioc is off the cards, for now, admiring the tall trickles and sculptural masterpieces here is just as good.
