For those who do NOT have a car:
Lednica Górna is boarded by Wieliczka on a road to Gdów. With lack of car you can get to Wieliczka from Kraków by "Contra" or "LUX" bus (station in Krakow is near main post office, in polish: "Poczta Główna"). Contact with me and I can pick you up in Wieliczka or I can pick up and deliver your pet from/to Krakow.
