Things to do

Montreal is bilingual and split in two: the old town by the river keeps stone warehouses, while the Plateau and Mile End to the north live on cafés, outdoor staircases and music. The centre is compact, the metro links the shores and Mount Royal gives the view.

Old Montreal

Cobblestones lead from Notre-Dame Basilica to the Old Port waterfront. Step inside the basilica for the deep blue vault, then follow the water and turn inland along the Lachine Canal, where a path runs beside it.

Mount Royal and the Plateau

Climb Mount Royal on the path from Peel Street to the Kondiaronk lookout. Come down to the Plateau, walk Avenue du Mont-Royal and eat lunch on Rue Saint-Denis.

Jean-Talon and the Olympic Park

Jean-Talon Market fills a block north of Mile End with cheese, maple syrup, vegetables and fish. The metro runs from there to the Olympic Park, the Botanical Garden and the Biodôme, worth a couple of hours.

Where to stay

Old Montreal

Old Montreal suits the first days: basilica, port and museums are close. Visitors thin out in the evening, the stone streets empty, and residential blocks begin beyond the canal.

The Plateau

The Plateau draws people with cafés, outdoor staircases and Lafontaine Park. French is the everyday language, streets stay lively at night, and the centre is twenty minutes away.

Mile End

Mile End joins bakeries, music clubs and bookshops along Boulevard Saint-Laurent. It is calmer than the centre, though parking becomes a puzzle in the evening.

Getting to and around Montreal

Montréal-Trudeau airport connects to the centre by bus 747, which runs to Berri-UQAM station. Four metro lines, buses and BIXI bikes cover the city, and the REM light rail links the centre with the South Shore. Old Montreal and the port are best on foot, and Mount Royal is climbed on trails.

Three days in Montreal

Old Montreal and the port

Start at Notre-Dame Basilica, cross Place d'Armes and walk down to the Old Port. After lunch take the Lachine Canal path and finish at Bonsecours Market.

Mount Royal and the Plateau

Climb to the Kondiaronk lookout in the morning and come down through the park to Avenue du Mont-Royal. Cafés and shops fill the day, and music fills Mile End at night.

Jean-Talon and the Olympic Park

Morning at Jean-Talon Market for cheese and pastries to carry. Then the metro to the Olympic Park, the Botanical Garden and the Biodôme, with dinner on Rue Saint-Denis.
