Montreal’s Underground City (Montréal Souterrain) is a vast indoor complex that extends across a large portion of Downtown Montreal. Subterranean tunnels connect malls, hotels, cinemas, theaters, offices, museums, banks, universities, and metro stations, serving as a warm refuge during the city’s brutal winters.
With some 20 miles (33 kilometers) of tunnels, 190 access points, and thousands of shops, the Underground City can be something of a maze, especially to the uninitiated. To avoid getting lost, consider joining a guided tour. Tours of the complex show off highlights of the underground realm, which features everything from shopping malls to public artworks and even a segment of the Berlin Wall.
Some tours split their time between the Underground City and the ground-level attractions of Downtown Montreal, stopping at landmarks such as Christ Church Cathedral and the monument-dotted Dorchester Square.
