Special thanks to Andrew for being our first guest contributor and sharing some of his adventures at the zip line to Hell (Louisville Mega Cavern) in Kentucky (USA), the only fully underground zipline in the world.
Follow Taylor Avenue past a strip mall, fast food restaurants, ordinary homes and keep driving. Soon you’ll be winding through a business park and wondering if you’re in the right place. It seems unlikely but nestled behind rows of warehouses is a massive man made cavern with a zip line course.
