Alun is a WONDERFUL guide. Our group was small and intimate, and he has such a depth of knowledge and passion for educating people about Dachau. He guided us on and off the public transport without a hitch, gave us time to look at the museum with his advice on timings, and took us round Dachau in a way that meant we got to experience the minimum amount of crowds and the maximum time seeing the buildings and talking about the camp history. I cannot recommend Alun highly enough - you simply must take this tour.
