Spanning over 101 hectares in the heart of Marina Bay Sand, Gardens by the Bay nature park is the crown jewel of tourism in Singapore. It has now developed into an iconic tourist destination with over 50 million visitors per year. The park comprises three gardens in the waterfront: Bay East Garden, Bay South Garden, and Bay Central Garden. There is a Supertree Grove that contains 18 tree-like structures with a height range of 25 m to 50 meters. These vertical gardens are not just for aesthetic beauty. They perform functions like planting, giving shade and also working as environmental engines. A wide collection of plants find a home in these structures. Flower Dome —the largest greenhouse in the world — can also be seen in the Garden by the Bay. Other attractions include Cloud Mountain, The Lost World, Children’s Garden and so on.
