Known primarily as the only place in the U.S. that manufactures Corvettes and for the large ancient cavern that sits in the center of the city, Bowling Green has built a thriving tourist business on cars and caves. At the General Motors Corvette Assembly Plant, visitors can see the step-by-step production of America's favorite sports car. The Corvette Museum includes one-of-a-kind prototypes, that were designed but never manufactured, among other Corvette memorabilia. To view awesome creations made by nature head to the Lost River Valley and Cave. Take the underground boat tour, on the shortest deep river in the world, to see a land formation that is more than 10,000 years old and has been used as shelter by Native Americans and Civil War soldiers. Though Bowling Green never officially left the Union, it's home to a number of historic war landmarks, exquisite old homes and remarkable buildings that can be visited on foot or by car during a leisurely drive through this beautiful part of the country.
