Wieliczka Salt Mine is one of the most precious and fascinating Polish monuments. The first tourist trail in Wieliczka was established as early as the beginning of the19th century. A couple of centuries later the salt mine was designated as one of the first UNESCO World Heritage Sites (1978). The underground path leads through numerous drifts, galleries and chambers, where traces of mining activity have been preserved, as well as examples of art, theme compositions relating to the history of the mine and its legends. Wieliczka is the world's largest mining heritage museum with a collection encompassing unique pieces of mining equipment reflecting the development of mining techniques from the Middle Ages until today. Moreover, the microclimate of the mine has a beneficial impact on visitors who suffer from asthma and allergies. The tour starts with a descent of 64 meters by stairs. The trip finishes at the level of 135 meters below the surface and the return to the surface is by lift.
