It was a little chilly when we got down to the caverns! It was about a 2 hour tour of the entire cavern. The waters were so still, they looked like mirrors with the way the cavern was reflecting off of them! So beautiful! There was an organ/piano in the middle of the caverns and it started playing music. Pretty neat!! We didnt get to capture much pictures because we didnt realize that the memory card was full! Lesson learned, always check the memory cards and batteries!
