Entrance to the zoo is with discount 26SGD. But the Singapore Zoo has plenty things to offer. It is a huge zoo with many many different animals. It took us 3 hours to go around, and we didn't dawdle (waste time). And most of the animals aren't in a cage. There are often natural obstacles which keep them in place. That gives a nice view for the visitors. On picture 2, you can see a big lizard just walking around on the path. I went to the zoo with Misaki from Japan and Olli from Finland.
