Fodor's Expert Review Brookfield Zoo

There are more than 2,000 animals at this gigantic zoo and highlights include the 7½-acre Great Bear Wilderness exhibit, a sprawling replica of North American woodlands for the zoo's population of grizzlies, polar bears, bison, Mexican gray wolves, and bald eagles. Watch the polar bears from the popular underwater viewing area. Elsewhere, monkeys, otters, birds, and other rain-forest fauna cavort in a carefully constructed setting of trees, shrubs, pools, and waterfalls at Tropic World, while at the Living Coast you can venture through passageways to see sharks, rays, and Humboldt penguins. 

One of the best educational exhibits is Habitat Africa, where you can explore the dense forest section, with animals like the okapi (an animal that looks like a cross between a zebra, giraffe, and horse). In the savannah section, which has a water hole, termite mounds, and characteristic rock formations, you can spy such tiny animals as the 22-inch-tall klipspringer antelope.

The Swamp is about as realistic as you would want an exhibit on swamps to be. It has a springy floor and open habitats with low-flying birds that vividly demonstrate the complex ecosystems. For hands-on family activities, visit the Hamill Family Play Zoo, where kids can play zookeeper, gardener, or veterinarian. Special events—most notably Holiday Magic, which lights up the zoo on select December evenings—are also worth checking out. If you don't want to trek around the 216-acre property, don't worry. You can hop aboard a motorized safari tram ($6) on weekends in warm weather months.
