Tennessee Aquarium

DOWNTOWN. The world's largest freshwater aquarium is home to more than 9,000 creatures. The museum takes visitors on a tour of the Tennessee River ecosystem, from its genesis high in Appalachia to its mouth in the Mississippi Delta. Along the way you'll view alligators, ducks, frogs, eels, snakes, and otters, to name a few. There is also a lake sturgeon touch-pool. The tour through the aquarium is self-guided, but guides are located at every exhibit to answer questions.
