Kartchner Caverns

[kjscrafts]

This is an interesting caverns to visit. I have not been to many caves, yet (going to many on a road trip soon), but so far this seems to be one of the best open to the public. The nicest thing about it is that since it is a state park it is not overly touristy, but rather more of a fun educational experience.

The closet thing to a cave, that I have ever been in, was an old gold mine up in Cripple Creek, Colorado.

I bet caves are a bit safer!
