We love the way Singapore Zoo has been designed; there isn't a cage in sight. For the most part, all that separates the wildlife are dry and wet moats, rock walls and streams. You can sit with the Orangutans, gaze at a Polar Bear flopped down next to his ice cave and feed the Elephants. The zoo, which turned 40 this year, has over 2,800 animals. If you tire of walking around the 26 hectares these creatures call home hop onto a tram and experience the zoo at your own pace. Then, head over to the River Safari and don't forget to get to the giant pandas, Kai Kai and Jia Jia, and make a stop at the Squirrel Monkey Forest, too, where the little ducks are free to run around you. After the entertaining Creatures of the Night show, hop onto the run for the 40-minute guided Night Safari.
