There's a reason this zoo is touted as the best in the world. For one, it's huge, and you'll walk miles to cover the whole zoo by foot. Second, it has the largest animal collection I have ever seen in a zoo, and I'm sure it's up there in comparison with other large zoos in the world. Third, there are a bunch of ancillary experiences you won't get in other zoos, such as Skyfari (a gondola the spans the East and West parts of the zoo). You can easily spend the entire day here.
