The Rivière Bécancour flows through the Centre-du-Québec region and is a navigable waterway accessible to canoeists, kayakers, and paddleboarders. It is part of Canot Kayak Québec's La route bleue network, which has established certified circuits in the Région de L'Érable specifically designed for paddlers of varying skill levels.

Two primary circuits are available along the Bécancour. Route A is a 13.6 km one-way trip running from Princeville to Lyster, suitable for those seeking a point-to-point experience. Route B covers 6.8 km and is rated beginner level, allowing a round trip from the Lyster municipal boat launch. This second option is characterized by weak currents and calm water, with several islands along the way. Although the islands are privately owned, they offer notable views along the route. The paddling season runs from mid-June to mid-October. There is no charge for the activity itself, though access to certain launching sites may be subject to a fee.

Along the routes, educational panels have been installed at various points, covering topics such as the historic use of the river by early settlers, Aboriginal occupation of the territory, Abenaki canoe traditions, and the river's bird and fish life. The river has historical and cultural depth that paddlers can engage with directly on the water.

In terms of ecology, the Bécancour acts as habitat for several endangered or precarious species, including waterfowl and wood turtles. Invasive exotic species are present, including Eurasian watermilfoil, purple loosestrife, and common reed. Bank erosion is a noted concern along the river and its tributaries, with limited vegetated riparian strips contributing to water contamination from runoff and occasional landslides.

Water quality is a documented issue on the Bécancour. The river has been identified as carrying mining residues, and water quality concerns have been significant enough to compromise swimming. Paddlers should be aware of these conditions when planning trips, particularly if they intend to have any contact with the water.
