I believe that the closest grotto to Myrtle Beach, South Carolina is the Triangle Troglodytes Grotto in Raleigh, North Carolina. This is about a 3 hour and 20 minute drive. However, the Augusta Cave Masters Grotto in Augusta, Georgia (the second closest grotto to Myrtle Beach) is closer to the best caving (known as the TAG region where the states of Tennessee, Alabama, and Georgia come together) but it takes about 20 minutes more to get there. The state of Georgia is also where the deepest pit in the continental United States is.
