Here’s a type of unusual museum you may not have thought of: a salt mine. Not only will you learn the history of one of life’s most important elements, and you get to do it underground.

One of the more famous salt museums is the Wieliczka Salt Mine near Krakow, Poland.

Here, there is nearly 125 miles of passages several hundred feet underground, including a museum, and enormous chapel where everything is carved out of salt, and even life-sized salt statues.

A little closer to home is the Kansas Underground Salt Museum, which sits 650 feet below the town of Hutchinson.

Put on your hard hat and take an elevator down 65 floors where you can hop on a tram ride and then wander through more than 100,000 square feet of tunnels and passages.

And if you want to do more than just tour a salt mine, head to the Galos salt-iodine caves in Chicago.

For $15, you spend 45 minutes underground in a room made entirely out of salt from the Black Sea, which is supposed to replicate the health benefits of seaside climates.

And here, if you have a group of 8 or more, you can even book dinner inside the salt caves.

Now that’s what I call a high-sodium meal.
