Visiting Krakow was the highlight of my visit to Poland. I enjoyed the city itself, especially Kazimerz, the Jewish Quarter with its synagogues and Jewish restaurants. Then there was Wawel hill, with the cathedral and castle, and the view over the Vistula. But the best was the Rynek with its stately architecture and the fantastic food stalls.
From Krakow I also visited, Bochnia, Auchwitz, Wieliczka, Kalwaria Zebrydowska, and the wooden churches in Debno and Powroznik.
