We had an indescribably brilliant experience on this tour. Nowa Huta itself was fascinating, and I'd recommend a visit to anyone visiting Krakow. BUT. Even better if you can do it on this tour. Our host, Tomasz, was hilarious, full of knowledge, and very generous with sharing his experiences growing up in Nowa Huta under communism, and since.
I did this tour with my 13 year old son and it was one of our absolute highlights from our trip to Europe from Australia. We will both remember it forever. There was plenty in the tour for my son, particularly in the way it was presented, and he absorbed way more on this tour than he would have in any history lesson or through any book. I learnt so much too. Strongly recommend!
