Performers from all over southern Wisconsin have come together this holiday season to take part in this charity event and use their voices to help worthy causes. You will be serenaded underground in the candle lit beauty of the North Cave while water drips and mineral deposits slowly grow around you. Our performers have a vast variety of talents and songs to share - some invite the audience to sing along with familiar holiday carols. Take a Caroling tour and sing along, or learn more about fossils in our Focus on Fossils tour. In natural caverns, as in cathedrals or other sacred settings, music blends with the silence, resonance, reverberation and echo of this unique environment. Come and enjoy the enchanting acoustics of the underground. Come experience the spirit of the Holiday Season in a whole new way!
