Getting Around Krakow
The best way to get around Kraków is on foot, especially as most visitors spend the majority of their time in and around the walkable Rynek Glówny area. While taxis will get you from A to B in a hurry, the public transportation system called MPK S.A. is an effective and cost-efficient alternative. Getting into town from the John Paul II (Balice) International Airport (KRK), located roughly 10 miles west of the city, is easy enough -- for less than $5 USD you can take the "Balice Ekspres" train. The train is another popular option for getting to Kraków; you'll most likely arrive in the dazzling Kraków Glówny train station located on Old Town's outskirts.
Express train service is available from Kraków to Warsaw (the trip is a little less than three hours), plus there are daily direct trains to Berlin, Budapest, Prague and Vienna, among other cities. And though you'll trade in comfort and time, you might also take the bus from the city to other destinations around Europe.
Bringing comfortable shoes to Kraków is essential. This especially holds true if you're staying in Old Town, where most sites of interest are a short walk away. Also, you'll find a lot of streets are closed off from traffic, so sometimes walking will be your only option.
Miejskie Przedsiebiorstwo Komunikacyjne S.A. (MPK S.A.) operates buses and trams that effectively shuttle residents and visitors around the city. A lot of travelers take advantage of the trams, if they are headed away from the Rynek Glówny area. While some of the vehicles are dated, others are brand new. The network can be a bit confusing, so be sure to grab a map.
Taxicabs are also plentiful and relatively cheap. You can go to a cabstand or flag a taxi down on the street, but it's possible to save 20 percent or more on fare by phoning ahead.
Having a car is usually more of a hindrance than a benefit, as tourists tend to spend most of their time close to the Rynek Glówny area. Traffic isn't really much of an issue, but parking is very limited and pretty pricey. For trips outside of the city center (to see the camps or the salt mines, for example), we'd recommend taking a shuttle service. Many hotels offer door-to-door service at a good price.
