Hundreds of feet beneath the surface exploring Mammoth Cave. Located in southern Kentucky, about an hour and a half from Nashville lies the oldest known cave system on Earth. 400+ miles explored thus far, still more to come. An incredible experience and in my opinion a must see! I did the Domes and Dripstones Tour, super cool! nationalparkservice #mammothcave #videography #videographer #kentucky #filmmaking #photographer #columbusohio #inspiration #columbus #travel #cave #caves #nationalpark
