The best zoos do a lot more than provide a place to see animals in captivity. They also educate visitors about animals’ lives and the issues affecting them, and they serve as ways to preserve and rehabilitate critically endangered species. America’s best zoos have come a long way from the caged enclosures of the past and instead provide open-air habitats in natural settings for many of the animals. Rare and common animals alike find safety and quality care in these facilities. Let’s find out what the 12 best zoos in America are.
1. San Diego Zoo, California

Considered one of the world’s best zoos and often named America’s best, the San Diego Zoo has a dedication to conservation. With more than 14,000 rare and endangered animals, it’s also an incredible wildlife experience.
2. National Zoo, Washington (D.C.)

One of the oldest zoos in the country, this one was established in the late 1800s to preserve species such as bison, foxes, and beavers that were fast-vanishing at the time. Today, it’s one of the few zoos in the country that has pandas, a hugely popular draw, although they are scheduled to return to China in December 2023.
3. Henry Doorly Zoo and Aquarium, Nebraska

Located in Omaha, this zoo has a reputation for outstanding animal care, conservation, and exhibit design. It also has the largest indoor rainforest in the country and the largest indoor desert and nocturnal exhibit in the world.
4. Animal Kingdom Theme Park, Florida

Part of the Disney grounds, this 580-park is built around an African safari theme. As part of its conservation mission, this zoo once helped a white rhinoceros born there become ready for reintroduction to Uganda.
5. Lincoln Park Zoo, Illinois

This Chicago zoo is one of the nation’s oldest and has one of its largest zoo-based conservation and science programs. Animal welfare is a top priority here, as are conservation missions all around the world.

7. Bronx Zoo, New York

With 265 acres and over 10,000 animals of more than 700 species, the Bronx Zoo is the largest metropolitan zoo in the country. You can also enjoy a treetops ropes course and ride a zipline over the Bronx River.
8. Cincinnati Zoo & Botanical Garden, Ohio

With animal exhibits and botanical gardens, this zoo has something for any outdoors lover. One of its top attractions is a pair of sibling hippos named Fiona and Fritz.
9. ZooTampa at Lowry Park, Florida

At just 24 acres, this Tampa zoo is relatively small, but it still is a home to Tampa wildlife and to 1,100 animals from Afrisca, Asia, and Australia. It’s also renowned for excellent animal care and for rehabilitating endangered animal species.
10. Denver Zoo, Colorado

The Mile High City’s biggest and best zoo hosts over 3,000 animals. Additionally, it’s active in protecting species under pressure from habitat loss, human encroachment, and catastrophic events.
11. Houston Zoo, Texas

A portion of every ticket sale goes to support wildlife conservation projects, including ones to help native Texas species. That and the more than 6,000 animals there help make it one of the most visited zoos in the country.
12. Austin Zoo, Texas

This zoo is small compared to most others on this list and not as well known, but it has a big mission. Many of the animals here were taken in when they were orphaned or abandoned as young or because they were suffering from neglect in less ethical zoos and wildlife parks. The Austin Zoo is also popular with locals because, after Christmas each year, the zoo accepts people’s Christmas trees, which they repurpose as habitats for some of the residents. There’s also a fun little train ride that kids and their parents always enjoy.
