Sungei Buloh Wetlands Reserve [sbwr.org.sg] is one of the few truly wild places left in Singapore. You can see quite a lot of wildlife there; monitor lizards, tree frogs, resident and migrant water birds and, I’m told, even small saltwater crocs on occasion. Unfortunately, I didn’t see a croc, but I did see lots of crabs and even a tree frog or two.
