This 2-hour, private small-group guided walking tour will lead you not only through the streets of the city centre but beneath through its RÉSO, known by Montrealers as the 'Underground City'. Accompanied by your guide, discover this effervescent area and learn about its history with your guide. When passing through the interior city and its tunnels connecting metro stations and buildings which feature nearly 1,700 boutiques, 200 restaurants, universities, cinemas, apartments, art centers, museums, arena and more, you will come to understand how 500,000 people per-day can go to work, the films, or even go shopping without having to go outside.
