A visit to Auschwitz is easy to plan. The camp is not very far from the airport of Katowice. A rental car is a must, but they are not really expensive in Poland. By car it's about 35 minutes drive to Oświęcim (the town where Auschwitz is located). Moreover, the trip can be combined with other places of interest like the city of Krakow. In Krakow are several WW2 places of interest, for example the former factory of Oskar Schindler which has been converted into a modern museum of the Second World War.
