A short easy drive from Nashville International Airport, Cave City, Kentucky is a good launching spot to visit Mammoth Cave National Park. It is just 90 miles from Nashville along Interstate 65 North.
After a trip to the caves for just $50 per canoe we launch on 7.5 mile down the Green River. From the Dennison Ferry to Green River Ferry this routes takes about 3 hours.
Mammoth Cave Canoe & Kayak offers other trips and no matter which one you choose, I am sure it will be an enjoyable experience.
