You'll probably catch this place on the way into town from the airport, there's an enormous and scary crocodile statue outside.
The park offers the usual in animal parks, with a good mix of education and cool animals. The one thing that makes the Crocodile Center worth the visit is the crocodile fishing bridge. You can buy a chicken breast to dangle on a rope for 10RMB, but the lazy crocodiles won't be interested. For a real frenzy, buy a live chicken for 50RMB. Maybe not a good idea for the young kids, but the jaded teens might love it.
