3. Luray Caverns – Virginia
Deep beneath Virginia’s Blue Ridge Mountains lay the largest caverns in the east. They’re home to some impressive rock formations including massive columns, hanging draperies covered in shimmering calcite, and even an underground lake.
But the real gem of Luray Cavern is the Great Stalacpipe Organ — also known as the world’s largest instrument. Listen as Electronically-controlled rubber mallets gently tap the cave’s stalactites, turning three acres of the cave into an underground performance space.
Admission to Luray Caverns is $26 for adults, and $14 for children ages six to 12. Included is a one hour guided-tour of the caverns, entrance to the nearby Car and Carriage Caravan and the Luray Valley Museum.
