The lower portion of this valley is served by Route 138 which runs along the shoreline of the St. Lawrence River. Route 170 which links Saint-Siméon to Petit-Saguenay village serves the lower and middle parts of this valley. The upper part of the valley has some secondary forest roads for forestry and recreation purposes.[2][3][4]

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

The surface of the Black River is usually frozen from early December to late March, however, safe ice movement is generally from mid-December to mid-March.
