Best time to visit Mammoth Cave National Park
Late spring through early fall offers the most reliable conditions for RV travel, with mild temperatures, open campgrounds, and the full slate of ranger-led cave tours. Summer is the peak season and cave tours frequently sell out, so reservations are essential. Shoulder months in April, May, September, and October bring smaller crowds, comfortable hiking weather, and vivid fall foliage along the Green River valley. Winter visits are possible since the cave stays a steady temperature year-round, but expect reduced tour schedules and possible weather-related road or ferry closures.

How to get to Mammoth Cave National Park
The park sits just off Interstate 65 in south-central Kentucky, roughly 90 miles south of Louisville (about a 1.5 hour drive) and 90 miles north of Nashville, Tennessee (about a 1.5 hour drive). Bowling Green is approximately 20 miles southwest of the park, making it a convenient supply stop for RVers. There are no high mountain passes or tunnels on the approach, but RV drivers should follow official park directions rather than GPS, since GPS and electronic navigation do not always lead visitors on the best path to the park, so it is wise to review the park's directions before setting out. The closest major airports for fly-and-rent trips are Nashville International (BNA) and Louisville Muhammad Ali International (SDF).
