Discover Montréal beyond the cold on a two-hour small-group tour of its Underground City, known locally as the RÉSO. Stay warm as you weave through the tunnels and mostly indoor passageways connecting downtown landmarks, public art and unexpected spaces, with brief outdoor sections along the way.
Meet inside Complexe Desjardins, downstairs in the main atrium near the large fountain. Look for the Explora Montreal flag and arrive 15 minutes before departure.
Walk through the underground connection to Complexe Guy-Favreau. Stop at the large RÉSO map for an Underground City 101: learn how to read the map, follow the signs and navigate the network confidently. Continue to the colourful Lipstick Forest at the Palais des congrès and the World Trade Centre, where you will see a piece of the Berlin Wall. Personal stories bring Montréal’s history, architecture and everyday life into focus.
At Square-Victoria–OACI, discover the distinctive Guimard Métro entrance before hopping on the Métro to Bonaventure. Learn how this busy hub connects the Métro, downtown buildings and the Underground City, then head up to 1000 de la Gauchetière to see its indoor skating rink.
Continue to Gare Centrale (Central Station) and board the REM with your guide for a round trip to Île-des-Sœurs, also known as Nuns’ Island. Return by REM to Central Station, then continue through the downtown connections to Place Ville Marie and finish at The Ring. Required Métro and REM fares are included.
With a maximum of 10 guests, there is time for questions, conversation and photos. Leave with a RÉSO orientation map, local recommendations and practical tips to keep exploring confidently throughout your stay.
Expect active walking, stairs or escalators and brief outdoor sections. Wear comfortable shoes and dress for the weather. Guests with mobility concerns should contact us before booking. This tour is bilingual in English and French.
