Tennessee's Lost Sea

I love caverns and living in Virginia has enabled me to explore numerous caverns. Today I read about a neat cavern in Tennessee. I know that it is not in Lynchburg, but since TN is a neighboring state, I figured it was fair game.

100 years ago, a 13 year old boy discovered an underground lake. The Lost Sea is the second largest underground lake in the world and receives about 150,000 visitors a year. The total tour takes a little more than an hour and includes a walk through the cavern culminating in a glass bottom boat ride across the lake.

It is about 6 hours from Lynchburg.
