Not usually a fan of zoos but this is definitely the nicest one I have seen. The 2000 animals are mostly kept in natural conditions, with moats rather than bars and cages. The night safari is a highlight, allowing you to see nocturnal animals as well as the others who haven't yet gone to bed!
MRT to Ang Kio station then bus number 138. Cost S$10.30.

If you join a tour check what time you will arrive, some get there too late.
