Many people in Saguenay-Lac-St-Jean only speak French. It's also important to note they speak French with an accent that might sound strange, even for other people from Québec. If you only speak English, you might encounter problems as you visit this area. Otherwise, most of this is true: Quebec#Talk
It's well known around Québec that people from the area use expressions you might not have heard before. Here is a few of them (in French, naturally.)
Cotteur - Possibly from the English "cutter"? Concrete demarcation between asphalted and non-asphalted land.
Faire simple - Being silly. Arrête de faire simple de-même, Stop being silly.
Froque - Jacket.
Plaisant - Fun, nice. C'est bien plaisant, It's really nice.
À cause used instead of pourquoi - Why. À cause tu parles de-même?, Why do you talk like this?
Robeur- From the english ruber, but meaning tires. M'a faire poser mes robeurs d'hiver bientot
Panel- Designates a mini van, or van in general. Viens-tu dans mon panel?
Colon- Having no style
Top- Cigarettes. Faut que j'm'achète un paquet de tops
You're most likely to arrive to Saguenay-Lac-St-Jean by land. If you're coming from Quebec City, you will cross the Parc des Laurentides on provincial road 175. This road is about 200 km long between Québec City and Chicoutimi and there is but one gas station (known as l'Étape) in the middle so plan ahead. It is also a great paronamic view of the deep Quebec Forest.
If you come from Chibougamau-Chapais or Abitibi-Témiscamingue, you will arrive by road.
There is also a few airports in the area. None of them are international airports, but if you're coming from somewhere else in Canada, you might arrive at one of them. The main one is Bagotville in Ville de La Baie (now part of Ville Saguenay). There is also one in St-Honoré-de-Chicoutimi.
A car will be required to drive around the area. Some cities in the area have bus systems, but most of them don't.
Saguenay-Lac-St-Jean has a big territory so be ready to drive long distances.
Les Saguenéens de Chicoutimi - The local hockey team on the Ligue de Hockey Junior-Majeur du Québec. They play at Centre George-Vézina. - http://www.sagueneens.com/
