Since it opened in late 2005, the world's largest aquarium has had Atlanta abuzz about its 8 million gallons of fresh and marine water, home to more than 100,000 animals representing 500 species from around the globe. The aquarium includes five stunning exhibits, including "Cold Water Quest," "Georgia Explorer," "Ocean Voyager," "River Scout," and "Tropical Diver," each featuring inhabitants of those environments. Crowds have been so big that tickets are issued based on your preferred time to enter the aquarium. Tickets to the 4-D theater are a few bucks extra. Advance booking online is highly recommended.
