I'm so glad I found your post. I'm excited to join.
These are the Supertrees of Gardens by the Bay in Sinapore. They are tree shaped vertical gardens which rise up to 16 storeys high. There are platforms around the top part of these trees where you can walk on to have a bird's eye view of the beautiful gardens below. Singapore is big on parks and greenery. In the evening, the lights here are magnificent! Too bad, I wasn't able to stay too long as we had plenty of places that we still needed to tour.
I took these photos with my Smartphone Oppo F5.
Is there a spiral staircase inside the "tree trunk" for access?
