The theme park has three aquariums, Ocean World, Polar World, and Coral World. It has the world's longest underwater aquarium tunnel (116m/380 ft.), and polar animals such as polar bear, polar wolves, penguins, and sea lions may make it a worthwhile stop. The Ocean World exhibit is set as a submarine cruising undersea and features a dolphin show. Call ahead for free English-speaking guides, who will explain which of the animals in the tanks are edible. Take bus no. 801 from Qingniwa Qiao to Medical University (30 min.).
