The sound and light show is pretty and free. We timed our visit so we could be there for that. Get there well before dark to get a decent seat.

It seems they change the theme of the show. When we were there they played a selection of Asian songs to accompany the lights.
The raised walkway between super trees is part of the show. We saw people watching the show from up there.
Here’s a slideshow to give you an idea of what the show is like. They run it at least a couple of times.
At the finale the nearby Marina Sands joins in the show.
Here’s a last look at the lights.
