DOWNTOWN. Explore the wild Australian outback, the Kenyan savannah, or the deepest, darkest Congolese jungle at this state-of-the-art zoo. The 200-plus acre complex is home to more than 1500 animals, including polar bears, apes, elephants, birds of prey, and more than a few big cats. An extensive renovation program in the 1990s added $71 million worth of improvements and took only five years to complete, doubling the zoo's area and tripling its population. Golf cart tours are available; reserve in advance.
