9. Singapore Zoo
Billing itself as the world’s best rainforest zoo, the Singapore Zoo is a pretty impressive place. The facility is clean and inviting, and the animals appear well treated, with plenty of lush vegetation and habitat space.
The orangutans are particularly impressive, and visitors can watch as babies and adults alike swing high above their platforms and snack on fruits. There is also a large chimpanzee family, zebras, meerkats, a komodo dragon, mole rats, white tigers, kangaroos, and many other creatures.
