Round out a trip to this unique spot with a stop in Bowling Green, Kentucky

For most families, summer break means either a staycation or an all-out trip that entails more logistical planning and money. If you're looking for something in between, a short overnight getaway to Mammoth Cave and Bowling Green, Kentucky, is an ideal compromise.

A road trip to the south central part of the Bluegrass State can include some outdoor adventure at Mammoth Cave National Park, underground exploration of the Lost River Cave and fun on wheels at the National Corvette Museum. Most places have seasonal hours that transition in spring, so be sure to verify operating hours before departing. Both cities are in the Central time zone, so you'll gain an hour when you arrive.

The journey starts with a four-and-a-half- to five-hour drive from Columbus to Mammoth Cave National Park. Spend the night in Bowling Green, Kentucky, and explore the city the next day before heading home.

This sample itinerary can be adapted to suit individual interests and budgets.
