Part of the mine is a huge storage facility used to store everything from hospital records to movie memorabilia. It is as about as safe as you can get! 650 feet underground the temperature stays a constant 68 degrees:
In spite of the touristy looking building, it is an active salt mine. We were far from the active mining though but we could hear charges going off occasionally and that was interesting!
The walls and ceiling sparkled with salt crystals and it is pretty! The salt in this mine is 96% pure.
Don't have to use toilets like the one below anymore;)
There is a museum at the entrance of the storage facility, which is, of course, off limits.
