If you are coming from Montreal, travel west (in the direction of Rigaud and Ottawa-Hull) on Highway 40. Once you hit Ontario, it will become Highway 417. Get off at Exit 79. The sign for Exit 79 says: "Limoges Road: Limoges, Embrun".
It takes about 90 minutes to get to Embrun from the West Island, 100 minutes from the Dorval/Saint-Laurent/Pierrefonds/Cartierville area, 110 minutes from the Mont-Royal/Centre-Ville area of Montreal, 115 minutes from Vieux-Montreal and 120 minutes from the Montreal-Est area.

Getting around Embrun by car is easy. Most of the town's tourist-related buildings and areas are accessible off the main road, called Notre-Dame Street.
While harder, one can get around Embrun on foot. The business park area in the western part of the town (near where Exit 88 hooks up with Embrun) has many stores fairly close together. However, walking from the western part of the town to the eastern part of the town can take almost an hour.
Traveling around Embrun by bicycle is quite convinent. In the western part of the town, a bike trail links several streets. In the central part of the town, a pedestrian lane on the side of Blais Street hooks up with the bike trail. From there, one can travel on Centenaire Street, a relatively traffic-free road, to get to the eastern part of the town.
Embrun is mainly francophone. 60% of the town's population speaks french at home.
While in Embrun, you can also visit the small town of Russell. Russell is a short drive away from Embrun. Russell is a beautiful town with a more rural feel than Embrun. To get to Russell, drive west on Notre-Dame Street. It becomes Castor Street, which leads into Russell.
