More than 420 animals representing some 140 species live in this 25-acre zoo, listed on the National Register of Historic Places for several buildings and other structures (including a moat) that were constructed of native sandstone during the Depression by WPA workers. Attractions include a Northern River Otter exhibit, a tropical rainforest, and a black-footed penguin underwater exhibit. You’ll find all sorts of reptiles and insects in the herpetarium; kangaroos and emus in the Australia Station; an excellent African lion exhibit; and endangered species such as cotton-top tamarins, prehensile tail skinks, and maned wolves. You’ll also see zebras, Malayan sun bears, and white-handed gibbons. Kids in a participatory mood should flock to Pioneer Farm, where they can feed a variety of rare domesticated animals, and to the Discovery Room, which features hands-on exhibits for all ages. Stop by the Watering Hole snack bar or the Wild Things gift shop, which boasts a better-than-average selection of animal-related items. Allow 2 to 4 hours.
