You will discover the Polish pearl, which has not yet become as popular as the Wieliczka salt mine. However, it is the mine in Bochnia that is the oldest developed salt deposit in Poland. You will find a fascinating journey not only deep underground, but also deep in history.A unique natural, historical and cultural monument can be visited only accompanied by a guide. The biggest attraction of the Bochnia mine is the world’s only ferry crossing of an underground chamber flooded with brine. Tourists cross the distance of 120 m in chamber flooded with brine, accompanied by two raftsmen, who spin colourful tales of the mysterious recesses of the Bochnia mine.
