Fodor's Expert Review Henry Doorly Zoo & Aquarium

Omaha's celebrated zoo has the world's largest indoor rain forest—the Lied Jungle—and a saltwater aquarium with one of the country's largest penguin exhibits. The zoo is also home to the largest nocturnal desert exhibit below ground. You can see more than 500 species of birds take flight in the zoo’s aviary, which, at 4 acres, is the world’s second-largest free-flight aviary. There's also an IMAX theater and a number of fun rides, including an aerial lift and a miniature railway.
