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.
Here are some of the best zoos in the US that you can visit.

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.
