Best Zoos in the U.S. to Add to Your Bucket List

There's arguably no zoo in the U.S. with more name recognition than San Diego's most famous attraction. But experts say besides its impressive size, the organization also lives up to its eco-conscious mission.

Even though they're meant to get guests up close and personal with animals, some zoos stand out for the hands-on exhibits that make them worth visiting.

"Lincoln Park Zoo in Chicago is completely free, a rarity when it comes to zoos across the country," Agnes Groonwald, travel blogger and creator of Travel on the Reg, tells Best Life. "While it's not as large as Brookfield Zoo in the Chicago suburbs, it comes with the historical heft of being one of the oldest zoos on the continent—it was founded in 1868! And because of its location, once you're done checking out the animals, you'll be close to some of the best views of the city, too."

In modern trip planning, the idea of an exceptional experience being completely free is becoming more of a novelty. However, some cities have prioritized keeping their exhibits open to the public at no charge.

For many people, the public's relationship with zoos has been in dire need of retooling. And in some major cities, local operations have been able to make good on keeping their most important inhabitants happy and healthy.

You can actually hit two of the best U.S. zoos while you're in New York City: There's another must-see spot at Manhattan's famed Central Park.

Thankfully, the best zoos in the U.S. have taken the opportunity to modernize in recent decades—and not just for the benefit of human spectators.

There are very few things that New York City doesn't do big. Experts say the Big Apple's most notable local zoo is no exception.

While there's no shortage of things to do around Portland, the city still stands out for providing a world-class zoo for visitors and residents alike.

Head to Omaha, Nebraska, and you can visit the Henry Doorly Zoo & Aquarium, which is consistently listed as one of the top five best zoos—not just in the U.S., but in the entire world.
