Second are the plains, which includes the Saint Lawrence Lowlands, which run from east to west and covers the northern portion of the Montmagny RCM, and is characterized by its arable soils. The Appalachians is the final geographic region of the area, taking up approximately 80% of the area. A series of peaks and ledges can be found here, and the Notre Dame Mountains dominate its landscape, which can reach an altitude of up to 850 metres (2,790 ft). Mixed forest covers the south of the RCM.

South River and its main tributary, Bras Saint-Nicolas, are two rivers that form the water system that drains into the Saint Lawrence River. To the east of the Notre Dame Mountains, the Daaquam and Northwest Black River feed into the Saint John River of Maine.
