Deux-Montagnes, Quebec: History, Things to Do and Travel Guide
Deux-Montagnes is a lakeside city in Quebec’s Laurentides, set where the Rivière des Mille Îles leaves Lac des Deux Montagnes. The city is compact, residential and commuter-connected, but its travel identity comes from the Grand-Moulin area, the river edge, new public access to the water and the old mill story behind the name.
A first visit should stay close to the water. The shoreline parks, Grand-Moulin history, paddling access, bike connections and REM stations explain Deux-Montagnes better than a drive through the suburban streets alone.
How Deux-Montagnes Started
Deux-Montagnes officially began on August 18, 1921, as the village of Saint-Eustache-sur-le-Lac. The municipal history notes that the new village had fewer than 300 permanent residents and that the first local settlement was concentrated in the Grand-Moulin district.
The name came later. The city says the toponym Deux-Montagnes is linked to the two hills visible from the northwest shore of the lake after the Sainte-Anne-de-Bellevue portage: Calvaire mountain and the hill at Saint-Joseph-du-Lac. The community changed from Saint-Eustache-sur-le-Lac to Deux-Montagnes in 1963.
Waterpower gave the early village its strongest local anchor. The Grand-Moulin name survives because mills once used the river corridor, and the city now interprets that past at Parc du Centenaire with a restored millstone dating from the 1830s. The river, road, railway and later commuter line all reinforced the same pattern: Deux-Montagnes developed as a small north-shore community connected to Montreal, Saint-Eustache and the lake country around it.
What Deux-Montagnes Is Like Today
Deux-Montagnes is now a city of about 17,900 people with a narrow waterfront geography and a dense residential feel. It is part of the Laurentides, but its day-to-day rhythm is tied closely to Greater Montreal commuting, schools, parks, local businesses and river access.
The return of REM service has made the station areas more important for travellers as well as residents. Deux-Montagnes and Grand-Moulin stations give car-free visitors a practical way to reach the community, though the best local stops still require walking, cycling or short rides from the stations.
The city also has a lived-in, local scale. Many of the waterfront places are used first by residents: families at playgrounds, cyclists moving between neighbourhoods, paddlers watching conditions, and commuters passing through the same station areas. That makes a visit feel less like an attraction checklist and more like a short look at how a north-shore city uses its river edge.
The city has a quieter visitor profile than larger Laurentides destinations. It is not built around hotels or resort attractions. Instead, Deux-Montagnes works as a riverfront stop with local parks, family cycling, paddling, neighbourhood restaurants, event spaces and easy transit access from the metropolitan region.
Things to Do and Places Nearby
Start at Parc du Centenaire, where the city has created a public waterfront space between chemin d’Oka, Grand-Moulin and the Rivière des Mille Îles. The park includes resting areas, a lookout, a children’s play area, historic interpretation, a launch for small non-motorized craft and a visible reminder of the Grand-Moulin mill story.
For paddling, use current information from the Parc de la Rivière-des-Mille-Îles. Its Deux-Montagnes site offers seasonal rentals for kayaks, canoes and paddleboards, with weather-dependent operation. This is the most direct way for visitors to experience the river as more than scenery.
Walk or cycle between the waterfront parks when conditions are good. The city is bordered by both the lake and the Rivière des Mille Îles, so short routes can include water views, neighbourhood streets and small park stops without needing a long itinerary.
Grand-Moulin is the best area for connecting present-day travel with origin history. The station name, road pattern, park interpretation and waterfront all point back to the same older river crossing and mill landscape.
If you are cycling, build in time for small pauses instead of aiming only for distance. Deux-Montagnes is most readable when you notice the shift from lake to river, the way chemin d’Oka carries traffic through the old settlement line, and how the newer transit infrastructure sits beside older residential streets.
Travellers with more time can use Deux-Montagnes as part of a north-shore day that includes Oka-area lake routes or the old village core of Saint-Eustache, but the local stop should lead with the river and Grand-Moulin.

Travel Notes
Deux-Montagnes works well without a car if the visit is planned around the REM and a compact waterfront route. Paddling rentals are seasonal and can close quickly in unsafe weather, so check the operator before travelling for the river. Summer and early autumn are best for cycling, paddling and parks, while winter visits are more practical for short walks, local food and transit-based exploring.
