The walk on the bridge is peaceful and fun. You will forget you are in Singapore, such a city with all the tall buildings. It offers you a magnificent bird's eye view of the topical plants, and some animals (well if you lucky enough) that live in the canopy. At your very eye level you will get to see the lively high life of the forest.
