Brookfield Zoo

Set on 216 acres, Brookfield is home to nearly 6,000 animals, including 3,000 invertebrates, representing 436 species. See Carver, the oldest-known wombat, and the orangutans, monkeys, gorillas and gibbons that populate “Tropic World,” one of the largest indoor animal exhibits anywhere. The rehabbed grizzly and polar-bear grottos, called Great Bear Wilderness, are among the many other attractions.
