Gardens by the Bay

Gardens by the Bay dominates the list with a 101-hectare waterfront garden that draws over 14 million visitors annually—more than triple the national population. Its Supertree Grove features 18 towering vertical gardens, while the Cloud Forest conservatory houses a 35-metre indoor waterfall, the tallest in Singapore. The Flower Dome, a 1.2-hectare cooled conservatory, sustains 8,000 plant species from five continents.
