Clarksville is in northern Tennessee near the Kentucky border, where two rivers meet. It is a growing city known for its friendly community and the nearby army base at Fort Campbell.
You can explore the Customs House Museum, splash at Liberty Park by the river, and walk the historic downtown with its old brick buildings and clock tower.
Clarksville's downtown has pretty old buildings, small shops, and the tall Customs House Museum with its fun hands-on exhibits for kids to touch and try.
The Cumberland and Red Rivers meet near town, and Liberty Park offers trails, a marina, and open grass for playing. It is a great place to watch boats.
