You want Jeff as your tour guide!

Jeff was our guide & was knowable as well as personable. He answered questions & took the time to get to know us a bit too. Our group got along with each other, so it was a fun, informative tour!

Great tour!

Amazing tour! I had no idea how fascinating Montreal’s Underground City was until this experience. The tour was informative, engaging, and gave me a completely different perspective on the city. Jeff was an outstanding guide! knowledgeable, passionate, and really entertaining. He explained everything clearly, answered every question, and made the whole tour enjoyable from start to finish. Highly recommend!

Great City Walking Tour

Great tour of Montreal! I recommend doing this tour early on during your visit so you can make use of the RESO (Underground network), subway system and use the network to comfortably move around the city. Ms. Catherine is very knowledgeable and is a great guide. This is a 2 hour walking tour with tons of toilette along the way.

Forward-looking urban planning in Montreal

Gets a lot of information about a prominent and long-term planning/solution of the urban environment that benefits all people both above and below the ground. Knowledgeable and friendly guide.

A nice tour through the underground

This was a fun tour and history of the underground. We were even able to navigate it to a metro stop a few days later!
