Montreal Underground City: A Practical Guide for First-Time Visitors

Montreal’s Underground City, known as the RÉSO, is a network of interconnected indoor spaces beneath downtown Montreal. For first-time visitors, understanding how the network works can make getting around downtown much easier, especially in winter.

What is the RÉSO?

The RÉSO connects shopping centres, hotels, office buildings, restaurants, metro stations and other destinations through an extensive network of pedestrian passages. It is particularly useful when the weather is cold or snowy because many parts of the route are indoors.

How should first-time visitors use it?

Start with a clear destination rather than trying to explore the entire network at once. Metro stations such as McGill, Bonaventure and Berri-UQAM provide useful access points. For a closer look at the main entry points, see our guide to the best metro stations for accessing the RÉSO.

Tips for exploring Montreal Underground

• Check your route before entering the network.
• Keep a map available because the passages can feel confusing at first.
• Use major metro stations as reference points.
• Allow extra time if you are visiting for the first time.

If you are unsure where to start, our guide on how to enter the RÉSO for the first time covers the basics of finding an entrance and getting oriented.

The RÉSO is best understood as part of downtown Montreal rather than as a single attraction. Combining it with nearby shopping, hotels, restaurants and metro connections makes it easier to plan a practical downtown itinerary.
