In continuous operation since the Middle Ages, the Wieliczka Salt Mine has always been recognized as much more than simply an excavation site. Listed among the UNSECO World Cultural Heritage Monuments, the site has been a popular destination since the late 17th century, drawing such names as Copernicus, Goethe and John Paul II, along with hordes of other people. One of the factors contributing to the popularity of this place is its microclimate, consisting of highly mineralised humid air and a temperature that remains at 7-12°C, regardless of season.

Other than the temperature, the Wieliczka mine surprises with its unparalleled set of beautifully decorated chambers (particularly worth seeing are the Copernicus Chamber and the Piłsudski Chamber), as well as the exhibits outlining the development of salt mining techniques since the Middle Ages. However, the most exciting attraction is the Blessed Kinga's Chapel, which you will find right at the bottom of the mine. This one-of-a-kind 19th century church is carved solely out of crystalline salt, including the holy figurines and chandeliers that light the chamber with a warm glow. Though not easily accessible, every Sunday the chapel hosts a traditional catholic mass, and occasional jazz and classical music concerts performed by local and international musicians.

At Wieliczka be prepared for quite a walk. The mine comprises some 2,040 caverns of various sizes laid out on 9 levels, the top level about 65 meters below the surface and the lowest as deep as 135 meters. The path leading through the numerous chambers and along lakesides is about 2 miles long, just a fraction of the unbelievable 300 km of known passages that make up the mine. That's why the tours offered at the Wieliczka Salt Mine usually last from two to three hours.
