The name "Chattanooga" comes from the Creek Indian word for "rock coming to a point". This refers to Lookout Mountain, one of the city's major attractions. Here visitors can explore extraordinary rock formations, see a roaring enclosed waterfall and travel by train to the top of the mountain for truly breathtaking vistas. Back down on the ground, don't miss the world's largest freshwater aquarium: the Tennessee Aquarium. History enthusiasts will love the city's museums dedicated to Civil-War, Native-American and 20th-century history. More than anything, Chattanooga is a scenic city, full of natural wonders waiting to be explored on foot or by car, bike or train.
