Wieliczka and Bochnia Royal Salt Mines by Els Slots
It is definatly worth a visit here from Krakow. The first time i visited the tour was in Polish and i was left a little disapointed but i went back a few months later and had a tour in English, which i could understand much better!, an i was really impressed. The main Chapple?Cathedral is hugly impresive it looks similar to most cathedrals but the entire thing i carved out of one giant piece of salt! worth the entrance fee alone!.
