It's located near Mount Horeb, which is west of Madison.
    
For the past six years they have had holiday concerts in the cave.

“The first time I heard music in here there was a group of tourists that were traveling that happened to be a singing group. And they noticed the acoustics just from the tour guide talking, myself, and did a little impromptu concert -- one in the back passage ways. And we thought, 'Wow!' Having the big voices, really resonate, it's just a wonderful,” said general manger Joe Klimczak.

The cave is not just a tourist site for the holidays; it's open for tours year-round.
