I took 100 Spires City Tours’ free “WW2 and Communism” walking tour (participants sign up in advance online and pay nothing except for whatever gratuity they feel is warranted, at the end of the tour), and it turned out to be one of the best walking tours I’ve ever taken in all my years of travel to destinations around the world. The group appeared to be smaller than the groups other tour companies were leading, and Kamil, our guide, spoke excellent English, presented his information in a lively, compelling, clear and understandable way, and showed us photos and illustrations that enhanced the experience. I came away with a much better understanding of World War II and Communism events and how they affected Prague and the Czech Republic. It added a lot to my appreciation of Prague during my visit. Thanks to Kamil, I also was inspired, even moved, by many of the stories. I talked to other people on the tour who also agreed it was outstanding. I am still enthusing about it to family and friends. Even if you're not a history buff, you will enjoy this tour, and so will preteens and teens. It is a not-to-be-missed tour if you are in Prague.
