Columbus Marina is located at the 335 mile marker on the Tennessee-Tombigbee Waterway, north and east of the John Stennis Lock and Dam in Columbus. This state-of-the-art facility has been awarded the “Clean Marina” designation, and offers boaters a well-located stopping point during their voyage on the waterway. Columbus Marina even offers those travelers wanting to come ashore a courtesy car to help aid in transportation to visit the City of Columbus.
