Since Singapore has many attractions for tourists to see and some of them might face troubles making a decision where to go first, next or last, so Singapore Zoo could be one of interesting choices for you to take a tour.

Singapore Zoo is situated on a promontory surrounded by the tranquil waters of the Seletar Reservoir, with the dense secondary forest beyond creating a perfect backdrop. It is one of the best zoos in Asia, if not the world. The animals are kept in spacious, landscaped enclosures, separated from the visitors by dry or wet moats. To spare yourself walking under the hot tropical sun, you can board a little train that trundles through the park. $14. The combination tickets to any two attractions cost S$25, while all three are S$30. It is easily to access by the Singapore MRT Subway. There are several food outlets, ranging from a burger bar to a more formal restaurant, and if you fancy taking a fluffy Malayan Tiger home as a souvenir (a toy one, not the real thing) there is also a gift shop.

Singapore Zoo opened on 27 June 1973 with a humble collection of 270 animals of about 72 species. The visitors are impressed not only with the Zoo's approach of displaying animals in their breeding groups, but also the manner in which different species together in one enclosure. This reflects the harmonious coexistence of animals residing together in the wild.
One of the more appealing attractions at the Zoo is the Animal Shows. The Animal Shows Primate and Reptile shows and Elephant & Sea lion shows started in the late 70s at various open areas within the Zoo. The Animal Shows are specially designed to incorporate the natural behaviors of the animals to educate visitors in an entertaining presentation. During the shows, conservation messages are disseminated to the audience to heighten their awareness of the environment. Furthermore, the shows are also meant to stimulate the minds of the animals and to help fight boredom.

Another major breakthrough for the underwater viewing polar bear exhibit enable visitors to "rub noses" with the Zoo's polar bears. Visitors are enthralled by the underwater antics of these graceful animals. Though only a young zoo with 20 years in existence, international standards in animal husbandry, maintenance and design have been attained.
If you want to have one of the greatest experiences you can have and have a day to spend, then I suggest you check out the Singapore Zoo.
