At Night Safari, electric trams glide past over 130 species, including tigers and elephants, with more docile creatures often passing within inches of the trams. Walking trails lead to enclosures inaccessible by tram, though sighting the animals can be a little hit-and-miss. (In truth, many are better seen at neighbouring Singapore Zoo.) If you've got kids in tow, the 20-minute Creatures of the Night show will thrill. Arrive at the zoo after 9.30pm to avoid the worst queues.
You'll need to catch a bus at around 10.45pm to make the last MRT train from Ang Mo Kio at 11.30pm. Otherwise, there are plentiful taxis out front.
