Tennessee Aquarium

Aquarium in Chattanooga

Occupying two side-by-side but separate buildings, this well-done aquarium is a fun and educational rainy-day destination. The River Journey building spotlights the inhabitants and ecology of the Tennessee River as it flows from the Appalachian Mountains to the Mississippi Delta. Exhibits in the Ocean Journey building showcase salt-water marine life – including piranhas! Crowd-pleasers include the river otters, penguins and lemurs, which swung their way into the aquarium from their island-bound Madagascar habitat in 2017.

There's also an IMAX 3D theater on the grounds.
