It was fun to see these trees up close, first by walking around the area which you can do for free. There are millions of green plants growing in these tree structures. And you can learn about how they are created by information panels around them. The skywalk had a fee, but it was a short wait one evening and then an elevator ride up. You are given fifteen minutes to walk the path and there is an employee who asks you to keep moving, but we felt like we had enough time to enjoy it and take photos. We were lucky and happened to be at the top when the Garden Rhapsody began (7:45 and 8:45 nightly), which was awesome - the lights and music make you feel like you are in a movie or on another planet. We finished our fifteen minutes and watched the remaining show from the ground which was just as interesting.
