The Rivière Nicolet Sud-Ouest is a calm-water river located in the Arthabaska Regional County Municipality of Quebec, flowing through the Kingsey Falls area in the southern part of the province. The river offers a paddling route of approximately 13 kilometres, making it a practical choice for a day trip by canoe or kayak.

One of the primary access points is located at Parc Marie-Victorin in Kingsey Falls, where a launch point provides entry to the river. The park is also known for its garden featuring large 3D mosaic sculptures, giving paddlers an additional point of interest at the put-in. The launch can be more challenging during periods of low water, and paddlers should exercise caution over rocks in the first 100 metres after entering the river.

The character of the river is generally calm throughout, and it is considered suitable for beginners. Beyond the initial rocky stretch near the put-in, the water settles into a quiet, easy-moving flow. Canot Kayak Québec has produced a set of three digital maps covering the full route, available free through the Avenza Maps app, which indicate put-in and take-out points, rapids, portages, camping sites, and other points of interest along the river corridor. The maps were published in November 2022 and are available for iOS and Android devices.

No specific regulations or permit requirements are noted for paddling this river. Paddlers planning a trip should consult the Canot Kayak Québec maps for detailed route planning, particularly regarding portages and any rapids that may be present along the full 13-kilometre stretch.
