Crystal Onyx Cave

Very intricate and beautiful cave system. It's not as well-advertised as Mammoth Cave, and honestly doesn't have the size, but that in no way takes away from its splendor.

Billboards announce, "Prehistoric Indian Burial Site." The cave was closed for several years, but now is open to visitors by appointment.
