Omaha's Henry Doorly Zoo and Aquarium.

Omaha’s Henry Doorly Zoo and Aquarium stands out for the sheer scale of its record-setting indoor habitats, allowing visitors to trek through distinct global environments in a single afternoon. Key highlights include the Desert Dome—the world’s largest glazed geodesic dome—and the massive Lied Jungle, an 80-foot-tall indoor rainforest. Beneath the desert sits Kingdoms of the Night, a sprawling nocturnal exhibit featuring a wet cave and an indoor swamp. Beyond these immersive ecosystems, the property features the Suzanne and Walter Scott Aquarium, complete with a 70-foot shark tunnel and touch pools at Stingray Beach. Spanning 130 acres, the grounds are vast enough to warrant a ride on the historic 1968 railroad or the open-air sky lift to navigate between exhibits.
