Gardens by the Bay including Supertree Grove and Cloud Forest, which has the tallest indoor waterfall in the world, plus the view from the top of the Marina Bay Sands Hotel.
I love the fusion of nature, concrete and technology in Singapore.
It sounds like a cliche but nature is a wonderful thing. It lifts my mood every time. Even though I started the day feeling down with jet lag I ended it on a high, literally and emotionally!
