Your Underground Adventure Awaits!  Enjoy these four tram tickets through Louisville's Mega Cavern.  The Historic tram tour is a fun-filled SUV-pulled tram ride that last about 60 - 70 minutes.  It covers history, geology, mining techniques as well as green building technology and how they recycle down in the Louisville Mega Cavern.  You will also see a replica of the historic Cuban missile crisis bunker.  It is about 58 degrees in the cavern year round, so light jackets are suggested.  Guided tours are offered daily except during November – January when the cavern is transformed into Lights Under Louisville.   Please make reservations and arrive 30 minutes prior to time scheduled.
