There are a few in and around Bowling Green. Beech Bend was first on the list. Google will help you find more.
This is very close to Mammoth Cave. There are campgrounds there.
15 minutes east of bowling Green is cave city, near mammoth cave national park. The park has camping.
Are you looking for tent camping or RV camping? There are some but I honestly recommend going about 20 minutes south towards Franklin.
