How to get to us?

Balice Airport is located about 15 km from the city center. The city center can be reached:

  • taxi access to the center takes about 20 minutes, the approximate cost of 60 PLN / 13 EUR
  • buses journey takes about 40 minutes, the approximate cost of 6 PLN / EUR 1,3
  •  the train is located about 200 m from the terminal, travel time of about 15 minutes, and an approximate cost of 20 PLN / 4,3 EUR, the trip to Krakow Central Railway Station and next by bus from West Station – bus number 179 to stop at AGH approximate cost of PLN 4 /1 EUR

You can also select a flight to Pyrzowice and then to Krakow by bus (which cost about 13 EUR). Another variant is the arrival to Warsaw Chopin Airport and from there by train ( InterCity Express or recommended) to Krakow (costs about 40 EUR). Krakow is one of the main railway hubs in Poland. Kraków’s Main Railway Station in the city center, near the historic Old Town district. Kraków has direct railway connections with many European cities. An express train ride from Krakow to Warsaw (about 300 miles) takes about 3 hours. The bus station is located on Veit Stoss ( the eastern side of the railway station).
