Located in Asheboro, the North Carolina Zoological Park, with more than 500 acres in its African and North American continental regions, is the country's largest walk-through natural habitat zoo, in which the animals and plants in its exhibits are seen in settings that closely resemble the habitats in which they would live in the wild. Its 37-acre African Plains exhibit alone is as large as many entire zoos. Sited on hilly, wooded terrain in the ancient Uwharrie Mountains of central North Carolina, the Zoo has approximately five miles of trails in its two continental regions. Among the Zoo's more popular animal attractions are its polar bears, seals, sea lions, seabirds, river otters, bison, elk, alligators, elephants, rhinoceros, chimpanzees, baboons, gorillas, giraffes, zebras, ostriches and tropical birds. There are dozens of other species as well.
