Bardstown to Cookeville Drive: Bourbon, Caves, and Scenic Highways

The drive from Bardstown, KY to Cookeville, TN spans roughly 120 miles along US-31E and I-65, taking about 2 hours without stops. But this route is far more than a straight shot; it traces the edge of the Interior Low Plateau, where Kentucky's famous limestone karst topography gives way to the rolling hills of Middle Tennessee. A little-known fact: Bardstown is home to the only fully functioning historic railway that also houses the Kentucky Railway Museum, a nod to the region's transportation legacy.

I-65 is well-lit and patrolled, but US-31E has limited shoulders and no median barriers. Use caution when passing slow vehicles. Recommended rest zones include the Barren River Lake Recreation Area, where a short walk to the dam offers a scenic break.

• Hidden off-route spot: Diamond Caverns, a privately owned cave with stunning formations, is 1 mile off US-31E near Park City.
• Family suitability: Mammoth Cave offers easy tours like the Frozen Niagara Tour, suitable for young children.
• Pet-friendly: Many Mammoth Cave trails allow leashed pets; check at the visitor center.

Local commerce along the way includes the Kentucky Down Under Adventure Zoo in Horse Cave, where kangaroos roam freely, and Jim Beam's American Stillhouse in Clermont, just a short detour north of Bardstown.

US-31E from Bardstown to I-65 is a well-maintained two-lane highway through rural farmland, with a speed limit of 55 mph. Transitioning to I-65 near Cave City provides four-lane divided highway at 70 mph. Rest areas and service stations are plentiful, especially around the Park City and Cave City exits.

• Fuel stops: Multiple gas stations at Cave City (Exit 53) and Horse Cave (Exit 58).
• Road quality: Mostly good, but watch for deer at dusk on US-31E.
• Cell service: Strong along I-65, spotty on US-31E through rural sections.
