Now, while answering the question of what is the best zoo in the U.S. is kind of tricky, it’s not hard to show you a shortlist of some of the best.

A list of just the top ten zoos in the United States wouldn’t quite be enough, so here is a list of the top 25 best zoos in the US, in no particular order.

Philadelphia Zoo

Declared the “nation’s first zoo”, Philadelphia Zoo is a much-loved institution that is easily one of the top zoos in the US. That honor is partly due to the fact that it is one of the oldest zoos in the US. Philadelphia Zoo opened in 1874, but was not actually chartered until 1859, before the Civil War – making it the first zoo. History isn’t the only interesting element of this zoo though, with many endangered animals counted among its nearly 1,300 animals. On its 42 acres you’ll find black and white ruffled lemurs, Amur tigers, and giant otters.

Recommendation: Gain free admission to 30 attractions and tours in Philadelphia, including the zoo, with the Go Philadelphia All-Inclusive Pass.

Bronx Zoo

New York is home to quite a few impressive zoos, but Bronx Zoo is without a doubt among the best zoos in NY. Found around the Bronx River, within the Bronx Park, the zoo covers 265 acres which makes it one of the largest metropolitan zoos in the country. Bronx Zoo opened in 1899 and began its long-established legacy of animal welfare and conservation when it created the first modern zoo animal hospital in 1916. Visiting today you’ll be able to see over 6,000 animals across 700 species among its exhibits, from typical favorites like tigers, lions, and gorillas, to smaller creatures like lemurs and reptiles.

To see all manner of animals native to California at one of the best zoos in America simply head to Oakland Zoo. Recently, Oakland Zoo introduced a new California Trail exhibit that focuses on native species like grizzly bears, grey wolves, and bison. But there are other exhibits and facilities as well across Oakland Zoo’s 100 acres, including a state-of-the-art veterinary hospital and a large butterfly garden. Oakland Zoo is now home to over 700 native and exotic animals, such as sun bears, reticulated giraffes, and hamadryas baboons.

Zoo Miami

Of the countless number of zoos across the country, Zoo Miami is the only subtropical one in the continental United States. If that doesn’t make Zoo Miami special enough, it also happens to be the largest and best zoo in Florida. Officially known as the Miami-Dade Zoological Park and Gardens, this zoo was opened in 1948 before it was relocated to its current location in 1980. The reason why it’s important that Zoo Miami has a subtropical climate is that it provides a natural warm and humid environment for the zoo’s animals which originate from across Asia, Australia, and Africa. These animals include exotic species like Malayan tapirs, komodo dragons, and Matschie’s tree kangaroos, as well as old favorites like gorillas and lions.

Omaha’s Henry Doorly Zoo and Aquarium

When it comes to the biggest zoo in the USA Omaha’s Henry Doorly Zoo can easily lay claim to that crown. That is if you take its combination of land area and number of species into consideration. This Nebraskan zoo, which started out in 1894 as Riverview Park Zoo, holds well over 900 different species on its 130 acres. Over its many years, Henry Doorly Zoo has made a name for itself as a leader in wildlife conservation and research. Visiting this beloved zoo you’ll have the chance to see rhinos, tigers, lions, and elephants, while its on-site aquarium lets you get up close to sharks and sea turtles.

Whether or not it’s the best zoo in Ohio, Columbus Zoo and Aquarium is certainly one of the largest zoos in the United States thanks to its 580 acres of land. Found in Liberty Township north of Columbus, this non-profit zoo first opened in 1927, although it has expanded over the years to include its very own 18-hole golf course. The sprawling grounds of Columbus Zoo and Aquarium is divided into eight groups of exhibits that each reflect a different geographical region of the world.

Founded in 1916 over in Balboa Park, San Diego Zoo has become a headline attraction for the city and is actually the most visited zoo in the United States.

To support its diverse wildlife population, the zoo is separated into eight exhibits, each with its own geography or habitat. In recent years one of San Diego Zoo’s more popular exhibits has been the Outback exhibit with its Australian creatures, including koalas and Tasmanian devils.

Since then, the zoo has worked hard to extend its conservation efforts beyond its animal population and runs global conservation programs on four different continents. Visitors to Denver Zoo help support these efforts and get to see more than 3,500 animals from 400-plus species. The zoo is still known for its bear population, but also for its Amur tigers, Asian elephants, and special Stingray Cove exhibit.
