The Rivière de l'Anse au Griffon flows through the heart of Forillon National Park on the Gaspé Peninsula in Quebec, Canada. The river runs through the scenic L'Anse-au-Griffon Valley, a landscape defined by wooded, mountainous terrain and dramatic coastal geography where the Appalachian highlands meet the Gulf of St. Lawrence. The Le Portage hiking trail follows along the river for much of its length, offering a sense of the riparian corridor that anglers will encounter — a mix of forested banks, elevation changes, and the rugged character typical of Gaspésie watersheds.
