8 Largest Zoos in the World

In the quest to identify the world’s largest zoo, the parameters of measurement become crucial. Size can mean anything from the acreage dedicated to the zoo’s layout to the diversity of species within its bounds. For instance, stretches of land like the Red McCombs Wildlife in Texas claim over 12,000 acres, yet their scope of biodiversity doesn’t match that of a traditional zoo, with only 20 species to their name. As such, a simple numerical approach does not suffice in capturing the scale and significance of a zoo.

The definitive list of the world’s largest zoos, therefore, is not straightforward—but a nuanced evaluation that appreciates both the expanse of their territories and the breadth of their species. These largest zoos in the world are more than just landmarks; they serve as pivotal centers for animal conservation, embodying efforts to protect diverse species and fostering connections between them and the human world. Such an exploration into these remarkable havens offers insights into their considerable size and, importantly, the substantial roles they play in global conservation.
