the unorganized territory of Lac-Ministuk of the same MRC;
the city of Saguenay (city).

The route 381 serves the western side of the Ha! Ha! River And cut the lower part of the "Bras Rocheux". A few other secondary forest roads serve the Arms of the "Bras Rocheux" Valley, especially for forestry and recreational tourism activities.
Forestry is the main economic activity in this valley; recreational tourism, second.
The surface of the Rocky Arm is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally done from mid-December to mid-March.
