Petites Îles River

The upper part of this valley is served indirectly by Route 170 which connects Saint-Siméon to the village of Petit-Saguenay which passes over the north shore of the Noire River. Despite its mountainous terrain, the valley of the "Petites Îles River" has some secondary forest roads for forestry and recreational tourism purposes.

Forestry is the first economic activity in the sector; recreational tourism activities, second.

The surface of Petites Îles River is usually frozen from the beginning of December to the end of March, however, safe ice circulation is generally from mid-December to mid-March.
