Summer in Nashville brings the heat—bright sun, high humidity, and bustling sidewalks from Broadway to the Gulch. But when the pavement starts to sizzle and the air turns heavy, there’s an unexpected way to cool down: head underground.
Middle Tennessee and nearby Kentucky are home to some of the most impressive show caves in the world, and they offer not only an escape from the sun but a chance to explore ancient, awe-inspiring landscapes—all at a refreshingly cool 55–60°F year-round.

Cool Down Underground, Heat Up the Night
