Incredible tour. My wife and I were the only ones booked for the day. Many operators would have cancelled, but this one did not. Adam, our guide and company owner, is very knowledgeable. We learned a great deal about the history of how concentration camps evolved, particularly in regard to Dachau. Though the tour itself certainly is a somber experience, it was also a privilege to walk the grounds and remember the many lives lost. Adam gave us plenty of time, and we never felt rushed. My wife has mobility issues, and he was able to arrange a mobile scooter for her at the visitor center. He also helped us find a shorter train ride back to our Airbnb. We have been on many tours in many places, and this one ranks among the best.
