The mission of the Great Saltpetre Cave Preserve Management Committee is to preserve and protect the natural resources of the Great Saltpetre Cave Preserve, maintain and restore those buildings and structures that are important or historically significant and in so doing, provide a pleasant and convenient haven for cavers while protecting a vital part of Kentucky history and landscape.
The Cave was discovered in 1798, and shortly thereafter the nitrate rich sediments began to be mined. In 1805, production was greatly increased so that 70 people were working all hours of the day and night to produce saltpetre, a primary ingredient in gunpowder. In 1815, saltpetre production ceased and the area was almost abandoned. Occasionally through the next century people would travel overland to visit the Cave. In 1938 it opened as a tourist cave, an operation that continued through the 1970's.
Great Saltpetre Cave is a natural attraction, the pathways are considered semi-strenuous, with slopes and uneven surfaces.
There are no steps from the cave entrance to Echo Auditorium and people in wheelchairs have traveled this route successfully.
The path from handicapped parking to the cave is about 110 yards and it is approximately 100 yards from the cave entrance into Echo Auditorium.
