Montreal’s Underground City: How to Get There, What to Do, and Why You Should Visit

Deep beneath the bustling surface of downtown Montreal lies a sprawling network that is much more than a shelter from frigid winters—it is a vibrant world of commerce, art, and everyday life. Known as the Underground City or RÉSO (from the French word réseau, meaning “network”), this 32-kilometer labyrinth connects vital hubs of the city, offering a unique experience unmatched by any other metropolis. Whether you’re escaping subzero temperatures, hunting for world-class shopping, or discovering hidden cultural gems, Montreal’s Underground City promises an urban adventure unlike any other.

What is Montreal’s Underground City (RÉSO)?

RÉSO (pronounced ‘reh-so’), Montreal’s Underground City, is the world’s most extensive underground pedestrian network, stretching over 32 kilometers (20 miles) beneath the core of downtown. More than just tunnels, this interconnected system links over 2,000 shops, hundreds of restaurants, hotels, apartment complexes, metro stations, museums, and even universities. Opened initially in 1962 with Place Ville-Marie, RÉSO has grown to reflect the ambitious spirit and adaptable nature of Montreal’s citizens.

  • Connects major downtown buildings, shopping malls, office towers, and transit hubs.
  • Provides sheltered passage—ideal during severe winter cold, hot summers, rain, or snow.
  • Encompasses public art installations, performance spaces, and interactive exhibits.
  • Known locally as “La Ville Souterraine” (the Underground City).

Rather than a single building or mall, RÉSO is an urban ecosystem built for convenience, comfort, and exploration. On an average weekday, more than half a million people pass through its corridors!

History and Origins

The development of Montreal’s Underground City can be traced to the construction of Place Ville-Marie, Montreal’s pioneering office and commercial complex, which opened in 1962. Driven by the need for an accessible downtown core protected from harsh winter weather, city planners envisioned a system of connected passageways. As construction boomed in the following decades, skywalks and subterranean corridors were added to connect shopping centers, office towers, and transportation hubs. The branding “RÉSO” was officially adopted in 2004, emphasizing the network’s unity and logic, and today RÉSO is a living testament to Montreal’s creativity and resilience.

How to Get There: Main Entrances and Navigation Tips

Getting to Montreal’s Underground City is remarkably straightforward. With nearly 120 access points—from metro stations to shopping centers and even university buildings—it’s possible to enter RÉSO from almost anywhere in downtown. Here are some tips for finding your way in:

  • Public Transit: The STM Montreal Metro system has multiple stations with direct RÉSO connections. Key stations include Bonaventure, McGill, Peel, Place-des-Arts, and Square-Victoria–OACI.
  • Entrances: Look for entrances at Place Ville-Marie, Eaton Centre, Central Station, Complexe Desjardins, 1000 de la Gauchetière, and Place Bonaventure.
  • RESO Signage: Once inside, follow the blue and orange RESO signs and maps. Major corridors are marked and maps are available throughout the system.
  • Walking Tours: Consider joining a guided tour for a deeper dive into architecture and history, starting from several central locations like 800 boul. René-Lévesque Ouest or the Maison du Festival Rio Tinto Alcan.
  • Accessibility: Most main passageways are wheelchair accessible, and public elevators/escalators are available in shopping centers.

Pro tip: Many visitors first enter via shopping malls such as Complexe Desjardins or Eaton Centre, both steps away from Place des Arts or McGill metro stations, respectively.
