The hamlet Matawin River (popularly designated "Mattawin") is located on the east bank of the Saint-Maurice River, in Trois-Rives, in Mékinac Regional County Municipality, in Mauricie, in Quebec, in Canada. In the past, Matawin River was a municipality. Today, the territory of Matawin hamlet is a sector incorporated to the municipality of Trois-Rives.
More specifically, this hamlet is located in Row II (South West), in the former Lordship of Batiscan. This hamlet is positioned in front of the Matawin island, 3.8 km upstream of the Five Island, 8.2 km upstream legendary Manigonce rapids and 18.4 km upstream of the mouth the Mékinac River. The mouth of the river Matawin is located one kilometer south of the island Matawin the Saint-Maurice River.
Due to its geographical position, along Quebec route 155, halfway between Grand-Mère and La Tuque, this resort offers access to various wildlife areas such as the Saint-Maurice Wildlife Reserve. Several providers offer hosting services and tourist activities.
The colonization of the territory began in the mid of 19th century, when the logging rights begin to be granted in Middle and Upper Mauricie by the Government of Quebec. Forestry has been the engine of Matawin economic development. In the 20th century, tourist activities (hunting, fishing, camping, boating, mountain biking, snowmobiles, observations of nature...) have grown considerably.
