Starting Point and Meeting Details

You’ll meet your guide at 800 Boul. René-Lévesque O, a central spot easily accessible by public transit. The tour ends at Place des Arts, also in the heart of downtown, making it simple to continue exploring or head back to your accommodation afterward.

Exploring the Underground Tunnels

The core of the tour involves wandering through key tunnels, architectural highlights, and public art of the Réso.

The guides do a great job of pointing out artistic and architectural hotspots, which adds a layer of appreciation beyond just walking through tunnels.

Outdoor Points of Interest

Although a large part of the tour is underground, your guide will also take you outside, giving you a chance to see points of interest in the downtown area. This mix provides a broader sense of how the underground system connects to the city’s streets and buildings.

The Experience’s Pace and Style

The tour is designed to be fast-paced, making it easy to see a lot in just two hours. Expect about 4 km of walking, including staircases and escalators, which mostly go downward into the tunnels. One review mentions that less talking and more stops might be preferred—so if you’re keen to explore at a more leisurely pace, don’t hesitate to ask your guide.

Authentic Feedback from Travelers

Several reviews highlight how useful the tour is for navigating Montreal independently afterward. One traveler appreciated how Martin, the guide, shared tips on how to use the Réso system to avoid the heat on hot days—something that’s priceless if you’re visiting during summer.
