Chicoutimi today, is one of the three "neighborhoods" of the new city of Saguenay, along with Jonquière and La Baie. Of the three, Chicoutimi is the one I found to have more shops and daytime activities, including restaurants, bars and shops. On the banks of the Saguenay River, you can for walks through a town that has a small cathedral, a convent which houses a historical museum and also a former paper mill, the remains can be seen for free, and you can visit the interior for a small fee of Canadian dollars. You can go to the tourist office to pick up a map of the place, and later go for a wander through the streets. On your way you'll encounter small interpretive signs, in front of buildings or historical tours of interest. There are also hotels for anyone who wants to stay in the area!
La Baie, which means in French, the Bay, is one of the three "neighborhoods" that make up the new city of Saguenay, on the banks of the river of the same name. The center of the Baie, on the waterfront, is an area divided in two, the west, the bigger is full of shops, restaurants and hotels and the east is more residential. In this side you can find the pyramid of HaHa, a great work of traditional art. Ther is also plenty of information about the local indiginous people and many things to do, especially in winter, including, snowmobiling, skiing and fishing and of course the beautiful scenery.
Jonquiere is the westernmost area of the new city of Saguenay. With several supermarkets, restaurants and shops, the peaceful town becomes quite active at night, especially the weekends. There is also a nice little church and a river nearby.
