We had the benefit of the Medieval Time detectives tour and it was incredibly worthwhile for us as a family. Both local and family friendly tour guides instantly developed a connection with our 7 and 9 year olds. I have been astounded at the impact of these tours for our children. They not only gained a deep understanding and appreciation for the sites in the Notre-Dame area, but have since used the skills gained from the games and riddles to apply them to other settings. I cannot recommend this company more highly.
