The lac à Mars is a fresh body of water in the watershed of the rivière à Mars North-West, the rivière à Mars and the Saguenay River. This body of water is located in the unorganized territory of Lac-Pikauba, in the Charlevoix Regional County Municipality, in the administrative region of Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada. Lac à Mars is located in the central eastern part of the Laurentides Wildlife Reserve.
Upstream of the port, industrial and urban area, the rivière à Mars valley is mainly served by the Consol Paper road. The rivière à Mars North-West is served by a few other secondary forest roads for forestry and recreational tourism activities.
Forestry is the main economic activity in the sector; recreational tourism, second.
The surface of the lac à March is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March.
