The forest road R0208 (North–south direction) serves the eastern side of Lac Le Marié and the upper part of Rivière aux Sables.

A few other secondary forest roads serve the vicinity of Lake Moncouche for the purposes of forestry and recreational tourism activities.

From there, the current goes up north for following the course of this last river to "Baie aux Sables", on the south shore of the Pipmuacan Reservoir.
