10 Best Zoos in the US to Visit in 2023

With around 470 zoological facilities licensed by the US Department of Agriculture, narrowing down a list of the best zoos in the US is tricky.

Nonetheless, I did my research, looked for the crowd favorites, added some of mine, and compiled a list.

Some of these zoos, you may have heard of or even been to, while others may sound totally new.

Either way, I hope this inspires you to visit one of them soon.

2. San Diego Zoo (San Diego, California)

San Diego Zoo

I mean, it’s the San Diego Zoo. What more needs to be said?

It’s one of the largest, most impressive zoos I’ve ever visited. We were fortunate to spend an entire day there in 2019 and we still didn’t get to see it all.

We were lucky enough to see the 3 giant pandas in the bamboo forest. But after 2 decades of staying 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 adorable red pandas are in the Asian Passage Zone.

As I mentioned, there are hundreds of zoos in the US, and we’ve barely scratched the surface. Here are some more zoos you might want to check out.

Special Mention to Our Beloved Pittsburgh Zoo

Look, I have to give a shoutout to my home zoo, the Pittsburgh Zoo.

I’ve grown up visiting it and I spend even more time there now as a mom of two young ones. It pains me to not include it in the top 10 list here because it really is a wonderful zoo.

If you’re in the Western PA area, definitely make the time to visit, and let me know what you think!

Pittsburgh Zoo

Essential Information

  • Address: 7370 Baker St, Highland Park, Pittsburgh, PA 15206
  • Tickets: Kids 2 and under are free. $19 to $23 for adults (13 years old above), $16 to $20 for children 2 to 12 years old, and $17 to $21 for seniors (60+ years old). Buy tickets online, especially if you’re visiting in Groups of 15+ (you can get a $17 max flat-rate discount regardless of ages). There is no parking fee at the zoo. 
  • Opening Hours: Park opens 9:30am and closes at 5pm during in-season (April 1 through October 31). From November 1 to March 31 (during off-season), zoo hours are from 9:30 to 4pm. Zoo members can go into the zoo as early as 9am.

Must-visit: Aside from the adorable red pandals, my favorite animals to check out at Pittsburgh Zoo are the regal Siberian tigers, black rhinoceros, Kunekune pig, and polar bear. 

For Kids: Pittsburgh Zoo isn’t the biggest zoo in the country, which means even small kids can walk the entire area and not get too tired. If they do get tired, there are strollers, electric scooters and other “safari wheels” readily-available to rent.

My kids and I love the Kid’s Kingdom – over 7 acres of Pittsburgh Zoo designed specifically for kids. It has a huge playground, petting zoo, and exhibits like the Meerkat Exhibit that are created for young, curious people. 

Animal Interaction: Make sure to go to the aquarium’s touch tank (where you can “pet” stingrays), or the kangaroo and deer area, where you can pet these friendly animals.

The Best Zoos in the US

Going to the best zoos in the country is a chance to spend time with family while learning about animals, but it’s so much more than that.

Keeping animals in captivity for the benefit and education of human spectators may be controversial, and so many US zoos have sought accreditation by independent organizations that have shown a commitment to conservation and research.

Choose from one of the zoos that are accredited by the Association of Zoos and Aquariums (AZA) to ensure that animals are treated humanely and that the zoos are heavily involved in conservation efforts.
