The petting zone in the children's zoo, which is located just west of the aviary, has all these things young kids love: sheep, goats, pot-bellied pigs (who really dig little hands petting them), turkeys, chickens, ducks. So your little ones will be fascinated and occupied, and you can relax a little. At the moment management is installing a wildlife carousel so that kids will be able to mount and ride such exotic creatures as lions and tigers, and endangered species like wolves and rhinos -- not just the same old circus horses. No extra charge for the children's zoo, which is included with the price of admission ($12 adults; $7 children). A fossil-dig site has opened near the aviary, so your little darlings will get to feel the tactile sensations of eggs and bones, and learn that all present birds are descended from dinosaurs.
