An authentic river town, Columbus is located on the Chattahoochee River where many of the city's attractions are concentrated. The Columbus Historic Riverfront Industrial District boasts several interesting sites on the east banks, including 19th century mills and iron works plants. The Riverwalk stretches for 12 miles, and can be best enjoyed by walking, biking, in-line skating or taking a riverboat cruise. Columbus' military history is evident through many related attractions such as the Civil War Naval Center and the National Infantry Museum. The Coca-Cola Space Science Center should be included on any itinerary, as the formula for this famous product was developed here.
