Informative and enjoyable to learn the origins and history of this wonderful network of underground shops and services. Martin, our guide , had a wealth of knowledge and insights to share. His presentation was lively and engaging, and he spent a brief amount of time getting to know each of the participants, then often personalized his presentation with facts and tidbits tying in what we were seeing with analogies to our home cities. Excellent tour!

You’ll want to start your Montreal trip with this tour! Matthieu was a wonderful tour guide. Very knowledgeable about the history and the beauty of Old Montreal. Nice group of about 16 people. He was happy to provide context and answer all questions

Very informative and enjoyable! Gabrielle did an excellent job not only with showing/explaining the underground and answering each of our questions, but with managing everyone’s language needs. It was my first tour of Montreal, and a great intro to this aspect of the city. Highly recommend!
