9 Best Zoos in the US to Visit in 2020

Narrowing down a list of the best zoos in the US is tricky, especially given that there are over 300 officially recognized zoos in the United States.

Instead of stirring up controversy by trying to label the best zoo out there, I’m instead going to show you a list of my favorites.

Some of these you may have heard of before, and others may be a total surprise to you. Either way, these are some of the best zoos you can find in the United States.

9 Best Zoos in the US

I’ve scrounged through dozens of travel blogs and took note of their most-recommended zoos in the US, adding some that I personally love. I hope this list inspires you to visit some of them.

1. Henry Doorly Zoo and Aquarium (Omaha, Nebraska)

The 170-acre Henry Doorly Zoo & Aquarium is hands-down one of the top zoos in America. There are trams and the Omaha Zoo Railroad to make your visit to this zoo double the fun.

This world-famous 100-acre zoo used to house 3 giant pandas at its own bamboo forest, where you can walk through the Panda Trek and see them up close. But after 2 decades of stay in San Diego, the giant pandas had to go back to China. Gao Gao, a male giant panda returned to China in October 2018. His “baby mama” Bai Yun and their teenager-bear Xiao Liwu went home next in April 2019.

Fortunately, the Panda Trek is still there with the adorable red pandas.

6. Columbus Zoo and Aquarium (Powell, Ohio)

Its ranking as the best zoos in the US may be debatable, but its title as the largest zoo in the country isn’t. The Columbus Zoo and Aquarium is so massive (at 588 acres) that it features a 22-acre Zoombezi Bay water park, 18-hole Safari Golf Club, summer campgrounds, a theme park, and a ton of other activities.

And as I mentioned on my post about the best aquariums in the US, this place has many impressive features, such as the 100,000-gallon coral reef exhibit and massive outdoor tank  at the Shores & Aquarium.

Columbus Zoo

9. Cincinnati Zoo and Botanical Garden

Opened in 1875, Cincinnati Zoo is the second-oldest zoo in the country (after Philadelphia Zoo) and was appointed as a National Historic Landmark in 1987.

Although it didn’t make the best botanical gardens on my list, the garden exhibits and botanical education events are an attraction on their own.

USA Today named the Cincinnati Zoo the top zoo in North America for 2019, after hosting a poll for the nation’s best zoos.
