Shedd Aquarium

Opened in 1930, Chicago's John G. Shedd Aquarium boasted the first permanent inland saltwater tank in the U.S., and for a time was the largest aquarium in the world. Today, its most impressive tank is a circular 90,000-gallon coral reef exhibit with sharks, rays and sea turtles. A huge array of aquatic and terrestrial life — ranging from sea horses to beluga whales, sea lions and some noisy penguins — provides a diverse setting perfect for hours of wandering.
