The Oceanarium is the largest indoor marine mammal exhibit in the world, and it's right here in Chicago.
Inside the Oceanarium's 170,000 square foot structure, visitors can view majestic creatures from both
above and below the water's surface. The Aquarium's researchers have also brilliantly recreated the
rugged shores of the Pacific northwest - its huge rock formations and trees. Its coves and inlets.
Visit the Oceanarium today. It's an ocean by the lake.
