Love this place!
So amazing!!! I loved it!!! You should definitely go!! But word to the wise, do not take children under 6! Its a FAR distance to walk, and it is very rocky terrain through out most of it!
You can also check out a live concert in the cave at the Volcano Room. http://www.bluegrassunderground.com/
Be prepared to hike in the cavern, very cool though. Literally cool stays like 58 degrees year round. Plan your trip right and you can camp in the cavern, very cool.
This was so cool, just be prepared to hike inside of the caverns. If you plan your trip right you can even camp in the caverns, really cool.
Go see some bluegrass in a cave!
Do the overnight wild tour! It's about an hour of spelunking and it's tight!
