Re: things to do in Tulsa Oklahoma hello annie, you need atleast 5 hours to spend at Tulsa zoo, because it has manythings to see. It consists of 70 acres with more than 1500 animals. This zoo has picnics facilities and a miniature train to tour around the park. It opens daily from 9am to 5pm, but closed on Third Friday in June & Christmas Day, so make your trip according to this. The cost od admission is free for kids 2 & under. For 3-11 years- $4 and Adults - $6. Hope this helps. |
