The Rockcastle Karst Conservancy, an organization dedicated to safe caving practices and land protection, owns three cave preserves in Rockcastle County, Ky. The group allows limited access to Misty Cave and Pine Hill Cave, but the Great Saltpetre Cave Preserve is closed. All preserves are closed from Nov. 1 to May 1 while endangered Indiana bats are hibernating. The conservancy requires cavers to submit a visitation form two weeks before their planned trip, and also requires at least one member of the party to be a member of the conservancy or the National Speleological Society or one of its approved chapters. Parties must be between three and 12 people, and any larger groups require special permission. More information can be found online at rkci.org
