You don’t need to be into gardening to appreciate Gardens by the Bay in Marina Bay. Take a scenic stroll beneath the 16-storey-high “supertrees” to appreciate this truly surreal site. The dedicated children’s gardens are a fun-filled, interactive wonderland and the water gardens are a great way to cool off in the heat. Note: it's free to enter the supertree grove but you'll need tickets if you want to stroll along the aerial walkway.
