Plage de l'Ile Saint-Quentin is a public sandy beach located on an island at the confluence of the St. Lawrence River and another waterway, within the city of Trois-Rivières, Quebec. The beach itself is approximately 1.92 kilometers long, providing a substantial shoreline for paddlers to access the water. Access to the island park and its parking areas is not free, requiring a fee. The beach is officially open and accessible daily during the summer season. Paddlers should be aware that this is a clothing-optional beach, which may influence the overall atmosphere during visits. The water quality of the St. Lawrence River in this area can be a significant concern, as the beach is subject to frequent closures due to high levels of fecal coliform contamination, particularly following rainfall events. For trip planning, the warmest months with the most favorable air temperatures are from June through September, though water temperatures during this period are not specified. The beach is situated within a larger park area that features pleasant walking trails, and it is a popular local destination for swimming and recreation. Dogs are not permitted on the beach. The surrounding views from the water are noted to be amazing, but weather conditions can change, so checking forecasts is advised. The clear, sandy beach offers a relatively straightforward carry to the water's edge for launching kayaks or paddleboards directly into the St. Lawrence River.
