Preacher’s Cave is not only a natural formation that’s worth seeing, it also has historical significance. When the Eleutherian Adventurers were shipwrecked on the Devil’s Backbone in the mid-1700s, they sought refuge in this cave. Religious services have been held at this site, on and off, since that time. Be sure to read the plaque at the entrance and walk right inside to get a feel for the size and to get a look at the natural “skylights”.
