Clarksville sits on the Cumberland River in northwest Tennessee, a river city shaped by soldiers, students, and the outdoors. Fort Campbell, the Army post just across the Kentucky line, brings military families to the area, and the 101st Airborne Division is based there. Austin Peay State University gives the city a campus and a downtown arts scene, and the Customs House Museum covers regional history in a former federal building. Dunbar Cave State Park, just outside town, offers cave tours, trails, and a lake, while the riverfront provides paths and a marina.
