Almost every large American metropolitan center has a zoo. Some are massive like Omaha's Henry Doorly Zoo and the Bronx Zoo, while others are small like the Cincinnati Zoo. Some are private like the Phoenix Zoo while others are public; some are free like the Lincoln Park Zoo and others charge admission. All of them bear witness to America's love of animals, both native and exotic.

We recommend that you call the attractions and restaurants ahead of your visit to confirm current opening times.
