Underground City of Montreal

Montreal's underground city, the RÉSO

The Montreal audio-guided tour takes you into the parallel world of the underground city, the famous RÉSO. This pedestrian network beneath the city covers more than thirty kilometres of tunnels and galleries criss-crossing central Montreal.

A city beneath the city

The RÉSO links many complexes: shopping centres, offices, universities, hotels, metro stations and railway stations. With an extent approaching thirty-three kilometres, it allows you to move sheltered from the harshness of the Montreal winter. The galleries house a wide range of shops and services, forming a true urban microcosm sheltered from the cold and snow.

What there is to see

You enter the RÉSO from many points, such as the World Trade Centre shopping mall. It is a typically Montreal experience to explore this labyrinth where you can shop, eat or move around without ever going outside. The underground city illustrates Montreal's ingenuity in the face of its harsh climate.

Practical information
