Go wild on an exclusive backstage tour of Disney's Animal Kingdom Park, courtesy of Limited Time Magic—experience the grounds of the park through the eyes of either a zookeeper or a veterinarian, all while walking about several behind-the-scenes areas! As the tour begins, half of the group will follow Animal Programs to get a glimpse of animal housing while the other half tags along with Animal Health to check out the state-of-the-art animal medical center. If you're lucky enough, you may even see a wild animal in the backstage environment! With only one tour per day, space is extremely limited—be sure to register at the Disney Parks Blog as soon as you can.
