The land forms and interesting geology created by nature are the main attraction of most caves tourists visit, and I do find geology interesting.

AS A TOURIST
In my non-spelunking state of mind, I have still visited a number of the famous caverns of the world as a tourist. Much safer and less exhausting. Below are photos (not mine) of formations in the Lechuguilla Cave, Carlsbad caverns, New Mexico.

When the narrow waterway opened into a great cavern, all the lights were turned off. It is totally black inside and the worms resemble stars on a clear night with no light. Absolutely amazing. Lots of drama without artificial lights.
THE PSYCHADELIC SALT MINE OF YEKATERINBURG, RUSSIA
As I said before, the fascinating thing about natural caves are the geologic rock formations, the culmination of millions of years of land shifting and water flow.
Salt Mines are a whole different experience from exploring natural caves. Salt mines may have been natural caves when the salt deposits were discovered, and they made have contained awesome formations inside, but they have been internally shaped by the way humans and their tools have removed the salt over hundreds, perhaps thousands, of years. The awesomeness of these caverns and tunnels is what the hand of man has revealed of nature’s wonders.
Carnallite can be yellow and white or even red, blue, or clear. The layers, sometimes containing magnesium and potassium (often used as an ingredient in plant fertilizer), paint rivers of color across the walls of this abandoned salt mine, dating back millions of years to when a salty sea dried up, leaving be-behind the mineral deposits. These had been mined for millennia and then for-

nights down in mines.
