50. Dinosaurs!
Don't miss the Lumpini lizards.
It may not be Jurassic Park, but Bangkok's version of Central Park -- Lumpini -- has reptiles big enough to give you a fright if you're not expecting to see one. The Varanus salvator (water monitor), which can grow up to nearly three meters (nine feet) in length, usually just ambles along the mud and grass around the water, but sometimes scrambles across a pathway to another pond. Don't worry, most of them are only about a meter (three feet) long. Most of them.
