Clarksville offers an affordable, walkable riverfront downtown with a lively food and craft-beer scene, outdoor recreation at the RiverWalk and Dunbar Cave, and a steady calendar of live music, festivals and university/military-driven events—easy to enjoy for several-week assignments without feeling stuck.
Big-city options are close: Nashville is about 45 miles away for concerts, airports and nightlife, and Hopkinsville, KY (roughly 30 minutes) adds extra dining and shopping.
