A great and very historical place. Must see when Y travel to Krakow. If Y wish to see real salt mine - select Bochnia: older, deeper, wilder and more genuine than Wieliczka but younger in museum role. If Y looking for attraction in "Disneyland" style - go to Wieliczka. If Y want to feel real salt mine with atmosphere, climate, style and original - take a trip to Bochnia. I was there several times always with positive experiences. It is a place for real adventure and Y can touch a real salt mine - priceless :).
