Gap Cave

Gap Cave is a major cave system at Cumberland Gap, with its entrance at the tri-state meeting point of Virginia, Tennessee, and Kentucky. With 18.5 miles of surveyed passage and six known entrances, it ranks among the longest caves in the United States and the world. Known since at least 1750, it was named by Dr. Thomas Walker and later became associated with Daniel Boone, saltpeter mining, Civil War-era military use, and tourism under the names King Solomon's Cave and Cudjo's Cave. After later ownership by Lincoln Memorial University, Virginia, and the National Park Service, restoration returned much of the cave to near its earlier condition.
