Welcome to Appalachian Underground

Join us for a day of underground adventure. We are a privately owned cave on restricted access property hidden in the Appalachian Mountains of Tennessee. Carter Saltpeter Cave is an amazing cave with many challenges and beauty. We descend 50 ft. from the cave entrance to the cave floor to a wondrous underground world of water falls and a small lake. There is something for everyone to spark the imagination.
