The polar bear passage is the Artic playground NEW to the zoo. It just happens to be the largest exhibit between Chicago and the West Coast. Nikita, the 4 year old, 750 pound polar bear loves the new exhibit and will wow you as the bear plays in his 140,000 gallon pool and 100 ton sandbox. Also visit the one year old Tropics Rainforest which opened last year. Besure to wear comfortable shoes, as the zoo is immense and has a great number of hills. You really can spend an entire day at this zoo. Brought to you by The Cone Team.
