I am reworking my planned trip to Europe this fall and dropping Munich due to distance so I have found my self with extra time that I can add to Poland. I will be arriving from Vienna and leaving Poland for Budapest. Any suggestions for places to see outside Karkow and Warsaw. I am thinking three days in each of these cities. I am planning on trips to Auschwitz and the salt mines. So I have two maybe three days to fill. I love history, art and culture. I will be using public transport. This will be in the second week of June.
