Largest Zoo in the World: Top Zoos by Size & Species Count

Zoos are a window into the incredible diversity of the animal kingdom. But with so many zoos across the world, it’s hard to know which one is truly the largest.

Some boast sprawling landscapes, while others host thousands of species. Conflicting information leaves travelers and wildlife lovers unsure of what to trust.

This guide uncovers the largest zoo in the world, categorized by size and species count, so you can explore the best of both worlds.

What Makes a Zoo the “Largest”?

The term “largest zoo” can be defined by some criteria or factors. Some zoos are big in size, or some are big in the number of animals. Various metrics are used to explain the largest zoo. Some of the most common metrics are:

1. Land Area

The area of zoo land is one of the key metrics for finding out the size of a zoo. It is specially used for open-range or safari-style zoos.

Example: The size of Hogle Zoo is around 42 acres. It is in Utah. The San Diego Zoo Safari Park covers about 1,800 acres.

2. Number of Species

The total number of species is often used to determine a zoo’s size and diversity. The big number of species that the zoo has means it is considered large in terms of biodiversity.

Example: Berlin Zoological Garden has 1,500 species, while San Diego Zoo has over 3,700. These zoos often include botanical gardens, adding to their species counts.

3. Number of Animals

Sometimes the number of animals is used to determine the largest zoo. It refers to the total population of animals within the zoo, rather than the number of species.

Example: The Berlin Zoological Garden (Germany) has over 20,000 animals across 1,500 species.

4. Visitor Experience & Unique Attractions

Visitor experience is key. It’s about immersive exhibits, unique encounters, and education. Cutting-edge exhibits, like walk-through aviaries or virtual reality, make zoos more attractive.

Example: Singapore Zoo features Rainforest Kidzworld and Wild Africa, offering diverse experiences.

3. Safari Zoos

• Safari-style zoos replicate African or savanna environments, showcasing regional species in open spaces. Example: The San Diego Zoo Safari Park. It covers 1,800 acres and has animals like rhinos, giraffes, and cheetahs.

4. Open-Range Zoos

• Open-range zoos offer vast areas and natural habitats for animals. They house species from around the world in spacious, semi-wild conditions. Example: The Lion Country Safari in Florida, which spans over 600 acres.

5. Aquariums
