Rivière Quisibis is a scenic river flowing through the Madawaska region of northwestern New Brunswick, Canada, winding through a landscape defined by dense boreal forest, rolling hills, and the rich natural character of the greater Saint John River watershed. The river is perhaps best known locally for trout fishing and its place within a broader outdoor recreation corridor that draws anglers, paddlers, and nature enthusiasts to the Rivière-Verte region. The surrounding area is steeped in Acadian culture and offers a genuinely remote, unhurried fishing experience far from the pressures of more heavily visited waters.
