There are a lot of companies offering tours to the salt mines at Wieliczka and some of them appear to be rather expensive. I opted to go by train and the ticket cost the grand total of 3.50zl (which is about 75p) to get there, which puts into perspective how much more expensive the tour companies are.
The train takes forty minutes and it’s the service which comes from (and to) Krakow airport. It’s nice and shiny both internally and externally.
The train was modern inside and there were power points available at the seats. I bought my ticket at the ticket office at Krakow’s main railway station, although you can buy the ticket at machines at both Krakow and Wieliczka. There’s also a ticket machine inside the train carriage, making this one of the smoothest ticket purchasing options possible, with cards and cash both accepted. It certainly puts some cities, not least Turin, to shame.
There are also numerous bus services which go to the mines, but for sheer convenience and low fares, I personally think that the train is the most efficient and comfortable way to go.
