This is the week the city decides it is genuinely good at fall. The UCI Road World Championships are launching Saturday. The Old Port gets its first-ever carnival next week. Free culture activities take over the city the weekend after that. You could fill the next ten days without spending much, if anything. Here is what to put on the calendar.

🚴 UCI Championships Fan Village: Free Family Activities All Week (Sept 20–27)

We covered how to watch the cycling back in August. What we want to flag now that the event is actually here is the Fan Village on Avenue du Parc, right at the finish line of all 13 races. It is free to enter, and it is genuinely designed with families in mind: interactive cycling challenges, mascots, big screens, food and drink options, and the kind of buzzing crowd energy that makes an outing feel like an event even if the kids have no idea what a peloton is. The race route through Mont Royal is also free to line, and the Camillien-Houde climb (bus 11 from Mont-Royal Metro) is the best free spectating spot in the city if you want to actually see cyclists close up, working hard. The whole thing runs through September 27.

📍 Where: Fan Village on Avenue du Parc near the finish line, downtown Montreal. Metro Mont-Royal (Orange line). Race route on Camillien-Houde, Mont Royal.
🗓️ When: September 20 to 27. All events free. Full schedule at montreal2026.org.

🛼 Tranquille à Roulettes: Outdoor Roller Disco in the Heart of Downtown (Through Oct 25)

Esplanade Tranquille in the Quartier des Spectacles is running as an open-air roller disco through October 25, with disco balls, retro-era video projections, and on-site skate rentals from Patin Patin. It is free to skate, and the Friday and Saturday evening sessions (open until 11 p.m.) have the most atmosphere if older kids are in the mix. Daytime sessions are lower-key and less crowded. One important note: the rink is closed September 24 to 28, which is exactly when the Old Port Fair opens and Journées de la culture runs, so plan accordingly.

📍 Where: Esplanade Tranquille, 1 Place Tranquille, Quartier des Spectacles, downtown Montreal. Metro Place-des-Arts (Orange/Green lines).
🗓️ When: Thursdays noon–10 p.m., Fridays noon–11 p.m., Saturdays 10 a.m.–11 p.m., Sundays 10 a.m.–10 p.m. Free admission, skate rentals on-site. Closed Sept 24–28. Full info at quartierdesspectacles.com.

🎡 Old Port Fall Fair: Montreal’s First Carnival at the Waterfront (Sept 24 – Oct 18)

The Old Port is doing something it has never quite done before: a proper carnival. Starting September 24 and running Wednesdays through Sundays until October 18, the waterfront between the stone buildings and the river hosts nearly two dozen rides, carnival games, food kiosks, and midway atmosphere against one of the better backdrops in the city. Admission to the fairgrounds is free; rides and games cost money, which means you can wander in and check it out before committing. The setting along Quai de l’Horloge, with the Jacques-Cartier Bridge in the background, is genuinely nice for this kind of thing. Worth timing around the sunset hours on a clear afternoon.

📍 Where: Old Port of Montréal, Quai de l’Horloge area, Old Montreal. Metro Champ-de-Mars (Orange line), then a 10–15 minute walk along the waterfront.
🗓️ When: September 24 to October 18, Wednesdays to Sundays. Free admission; rides and games paid. Details at oldportofmontreal.com.

🎨 Journées de la Culture: 2,000+ Free Activities Across Montreal (Sept 25–27)

This one runs every year across Quebec on the last full weekend of September, and every year families underestimate how good it actually is. The Journées de la culture is three days of free arts and culture programming happening in venues, courtyards, museums, and public spaces across Montreal and the province. Over 2,000 activities in total, and Montreal is the epicentre. Some specifics for the weekend: Place des Arts on Saturday the 26th has a free classical ballet discovery class (Studios GB of the Grands Ballets), a family sound session with the Orchestre symphonique de Montréal, and a free storytelling and music program from the Orchestre Métropolitain. The Musée d’art contemporain has free activities Saturday. And Esplanade Tranquille hosts the Fête du Quartier with outdoor family programming. The full searchable map of all activities province-wide is at journeesdelaculture.qc.ca.

📍 Where: Activities all across Montreal. Main hubs: Place des Arts and Quartier des Spectacles. Metro Place-des-Arts (Orange/Green lines).
🗓️ When: Friday September 25 to Sunday September 27. All activities free. Full program at journeesdelaculture.qc.ca.

🏛️ Pointe-à-Callière: The Age of Troy (Through March 2027)

Worth flagging for a rainy day or a weekday outing: Pointe-à-Callière, Montreal’s archaeology and history museum in Old Montreal, is running The Age of Troy through March 2027. It covers the Trojan War and the ancient civilizations connected to it through artifacts and reconstructions. Kids who have been through a mythology phase, or who will be soon, tend to respond well. The museum’s permanent exhibition, literally built over Montreal’s archaeological origins underground, is also strong. Admission applies; tickets at pacmusee.qc.ca.

📍 Where: Pointe-à-Callière, 350 Place Royale, Old Montreal. Metro Place-d’Armes (Orange line), about 5 minutes by foot.
🗓️ When: Open Tuesday to Sunday. The Age of Troy runs through March 7, 2027. Check pacmusee.qc.ca for hours and admission.

Gardens of Light at the Botanical Garden (through November 1) is also well worth the visit on a clear evening this month — tickets sell out on weekends, so book in advance at espacepourlavie.ca.
