HSBC Rain Vortex is the world's biggest indoor waterfall . It is situated inside the changi airport. So the first cool thing which i saw afrer landing to Singapore was this man made marvel.
It is an must watch thing in Singapore do not miss this at any cost . Also there are no charges you have to pay to watch this.
If you can wait till night then this magical waterfall gets converted into an muscial show with some real cool lightings .
I was lucky enough to witness this . Overall it was an amazing start to my Singapore trip .
