Fodor's Expert Review Milwaukee County Zoo

Inside this enormous park are more than 3,000 wild animals and birds—including several endangered species—plus educational programs, narrated tram tours, and miniature-train rides. Japanese snow monkeys occupy their own island, and the grizzly bears are reliably entertaining. The hands-on children's area focuses on dairy animals (this is Wisconsin, after all), but there are many other critters to pet and hold.
