Top 21 Largest Zoos in the World by Area

A zoo is the most important place for Wildlife protection and conservation. The Zoo is also known as an animal park or menagerie. The zoo is the abbreviation of Zoological Garden. Unlike, Wildlife sanctuaries and National Parks, Zoos do not provide natural habitat to the animals but they provide wonderful conservation services. From Asia, Europe, North America, and Africa, zoos are around the world to protect Earth’s wildlife and educate people about how they can help.

With the rapid extinction of the most vulnerable animals, zoos have become extremely important to protect wildlife. However, most of the zoos are only one or two acres large, housing only a handful of animals, while others are massive and are able to protect and keep animals from various environments.

We have done the research and curated this list of the largest zoos in the world. We also mention the timing and location of the zoo so that you will get complete information in one place. These monumental establishments showcase not only the immense biodiversity of our planet but also the efforts dedicated to conservation, education, and the preservation of endangered species.
