Singapore 2018 - Supertrees
One of the main features of Garden By The Bay are the Supertrees - a series of artificial trees ranging from 25m to 50m high. Totalling 18 in number, the trees act as vertical gardens as well as air-vents for the nearby Flower Domes. They also collect rainwater and generate solar power.
I had gone to experience the skywalk which link several of the tallest supertrees. There was a small queue to get up to the skywalk - which thankfully is via a lift.
If you have height fobia - this is probably not recommended. The skywalk is suspended and does move a little in the wind. But the views up here of the surrounding gardens are spectacular.
