The Shedd Aquarium is a great family destination, during every season in Chicago: spring, summer, fall and winter. The aquarium has unique fish exhibits that will appeal to children of all ages, including beluga whales and a Caribbean diving tank. Older kids will enjoy the 4D movies and Fantasea, the mystical dolphin show with its acrobatics and unique music. Younger kids will love running around the Polar Play Zone. The Shedd Aquarium is a Chicago landmark that is not to be missed when in the Windy City. As a tip, if possible, visit the Shedd with a Chicago resident - they get discounted tickets!
