While sights like Wieliczka may steal the limelight, due to it's proximity to the burgeoning tourist centre of Kraków, the Salt Mine at Kłodawa is a lesser known attraction that is absolutely worth a visit, especially if you're travelling through Greater Poland. Why? Firstly, it's the biggest mine system in all of Poland. Secondly, it's still very much in operation! Thirdly, it is the only mine in the whole of Europe that produces pink salt (y'know, the kind that we think only comes from the Himalayas!) However, it's the overall experience of touring through the mine system that is truly memorable. After descending the mine shaft via an elevator that travels at a dizzying 10km/sec, your journey opens up into the massive caverns of salt, lit with beautifully-coloured lighting to accentuate the size and ambience of this historic site. The track leads down numerous tunnel ways, tinged with strata of pink and white, and passage-ways lined with relics of mining technology that were previously used in this system. All the while you inhale the distinct aroma of 250-million-year-old pink salt, which they claim is rather good for your health! Most curiously, there are numerous places of worship along the way, and by far, the most moving sight during this tour is the Chapel of St. Kinga, beautifully carved out of salt and amazingly-preserved 600 meters below ground, where it still offers comfort and a symbolic light in the unfamiliar darkness of the mine shafts.
