Destination guide
Montreal: French North America, 90 minutes from New York
Montreal gives you Europe without the ocean: a walkable French-speaking city of stone streets, terrasses and festivals, reachable in an hour and a half from the Northeast. Air Canada, Porter and the US legacy carriers all compete on the route, so fares stay low.
Best time to visit: June to September is festival season and the terrasses are open — Jazz Fest in late June, Osheaga in August. May and October are cheaper and still pleasant. Winter is genuinely cold but hotel rates fall sharply and the Underground City makes it livable.
