Singapore Zoo , Singapore

Opened in 1973, this zoo uses moats and beautifully landscaped glass-fronted enclosures to house some 2,800 animals. 28 hectares (69.2 acres) of land is divided into more than a dozen regions, featuring 216 species, including rare and endangered ones. The world's largest captive orangutan group can be found here. Two programs, Wild Breakfast and Afternoon Tea, enable visitors to interact with and learn more about six species of animals while having their meal (extra charges apply). Photographic opportunities, of course, abound. Other highlights include feeding programs, elephant and pony rides, animal shows and a tram ride.
