In carrying out its mission of conservation, research, education and recreation, the Omaha Zoo has created Lied Jungle, the world's largest indoor rainforest. Visitors can also explore the Scott Aquarium, Desert Dome, Cat Complex and Hubbard Gorilla Valley and Orangutan Forest, or catch a film at the Lozier IMAX Theater. The zoo also offers train and tram rides, the TreeTops Restaurant overlooking the rainforest and a variety of other fun activities and attractions. For those who don't want to visit the restaurants, there are lovely picnic areas at the zoo, and snack kiosks selling refreshments. There are two ATMs at the zoo, but debit and credit cards are accepted.
