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 awesome 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 by foot, car, bike or train.
