Singapore's renowned 'open' zoo houses more than 3,200 creatures—including one of the world's largest colonies of orangutans—in progressively landscaped enclosures. Rock walls and streams replace cages, with feeding shows occurring throughout the day.

Next to the Zoo is the Night Safari, a tropical jungle by night. There are over 1,000 nocturnal animals from 100 exotic species to watch out for, including rhinoceros and hyenas. Strike out on your own along the walking trail or relax in a tram ride. Whichever you choose, the Night Safari is a fantastic adventure.
