[1] In the regions of Saguenay–Lac-Saint-Jean, Charlevoix, Côte-Nord, and Bas-Saint-Laurent, the park is situated along the eastern end of the Saguenay River and adjoins the Saguenay–St.

[3] Aboriginals, including Innus have inhabited the Saguenay Fjord area for thousands of years prior to the first Europeans arriving.

After Samuel de Champlain established a fort in 1608 on the northern shores of the St. Lawrence River (around present-day Quebec City), various Indigenous peoples, including Innu, Haudenosaunee (Iroquois), Huron, Algonquins and Cree all traded along the Saguenay River.

In addition to the depletion of the forests, difficult terrain and the decline of the lumber industry led to the Saguenay area remaining mostly undeveloped into the 20th century.

[6] Starting in 1970, the Quebec government began acquiring land around the fjord in hopes of protecting it.

[9] Animals that can be found in the park's forests include wolves, black bears, lynx, beavers, and moose.

Seals, brook trout, Atlantic salmon, as well as isolated populations of Greenland halibut and Arctic cod can be found in the park's waters.

Due to pollution on the Saguenay river, the beluga whale population has significantly decreased in the region.

[11] Activities in the park include over 100 kilometres (62 mi) of hiking trails, 50 kilometres (31 mi) of skiing trails, camping, kayaking, sea kayaking, a Bateau Mouche tour of the fjord, snowshoeing and ice fishing.
