The Zec Martin-Valin is a "zone d'exploitation contrôlée" (controlled harvesting zone) (ZEC), located in the Le Fjord-du-Saguenay Regional County Municipality, in administrative region of Saguenay-Lac-Saint-Jean, in Quebec, in Canada.

The reception office of the Zec Martin-Valin is located near the route 172 that connects the city of Saguenay to Tadoussac.

These expeditions in the northwestern part of the area include various portage trails and numerous lakes to cross.

Then they have to take forest roads on forty kilometers to reach the site of departures circuits in the North section of the Zec.

ZEC has made it easy access to the majority of water bodies in its territory by building parking lots and docks.
