The Serpentine River flows from the unorganized territory of Lac-Lapeyrère, Quebec,[1] located in the Portneuf Regional County Municipality, in the administrative region of the Capitale-Nationale, in the province of Quebec, Canada.

This river of Batiscanie has a length of 2.3 km (by water) from its source in Lake Genest.

After a tortuous path of one km to the southeast, the Serpentine River narrows to a segment of 200 meters.

Then she resumes her journey southeast of the lake to flow over 0.9 km, first in line, before turning south and then east.

The name "Serpentine River" is associated with the winding part of his course, especially for a significant segment of a dozen kilometers berries (on the north bank of the river) downstream of the road bridge (16th Street), built in the south of Lake Genest.
