The Montreal Underground City, known as RÉSO, covers 12 square kilometers. Finding your way through 1,600 stores and 12 metro stations can confuse new visitors. A walking tour provides structure and local context for your visit.
Why take a Montreal underground guided tour?
A guide keeps you oriented and explains the history of the 1962 tunnels.
Walking the 32-kilometer (20-mile) network alone is free but overwhelming. A local guide points out the public art funded by Quebec's 1% rule. You also learn how 500,000 daily users navigate the corridors without getting lost.
How much does a guided tour cost?
Standard walking tours usually cost around $25 to $36 CAD per person.
Prices change based on the provider and platform. Small-group tours start from $29.13 CAD to $35.69 CAD. A private 2-hour tour starts from $163.88 CAD. Always check current rates before booking.
Do tours include metro tickets?
Some tours include the required transit fares, while others do not.
Read the inclusions carefully before you book. For example, the Explora Montreal tour includes your Metro and REM fares. If your tour does not include transit, expect to pay ~$3.75 CAD per Metro ride.
Will we go outside during the tour?
Yes, most underground tours include brief outdoor sections.
Guides often take you to street level to explain how the buildings connect to the tunnels below. Dress in layers so you stay comfortable. The indoor sections are heated, but you need a coat for the outdoor portions.
What is the maximum group size?
Many top-rated tours limit groups to 10 guests.
Small groups make it easier to hear the guide in busy corridors. Tours by MTL Detours and Explora Montreal both cap their groups at 10 people. This provides a conversational experience as you walk through the complex.
Can I just explore the underground without a tour?
Yes, entering and walking through RÉSO is completely free.
You only need to pay if you ride the STM Metro. If you go alone, download a RÉSO map on your phone. First-time visitors should enter through major hubs like the Eaton Centre or Place Ville Marie.
