Plage de Longueuil is a municipal beach located on Île Charron within the urban agglomeration of Longueuil, Canada, on the shores of the Saint Lawrence River. This is a developed, urban beach primarily designed for swimming and sunbathing, which opened in 2016 and can see significant public use, having hosted nearly 25,000 visitors in one past summer. For paddlers, the beach provides direct shore access to the Saint Lawrence River. The main launch and take-out point is the beach itself, though paddlers should be aware that high water levels in the river can significantly impact accessibility. In the past, exceptionally high water levels have forced the closure or required reconfiguration of the beach area, sometimes reducing the usable zone. The Saint Lawrence River at this point is a large, powerful waterway, and paddlers must be prepared for its conditions, including strong currents and potential for wind-driven waves. People launching small craft have lost control in the river, underscoring the need for experience and caution. The water body's aesthetic is that of an urban riverfront, and paddlers can expect views of the Montreal skyline and the surrounding islands. The best season for paddling is summer, though water levels are typically highest in late spring and early summer, which can affect beach access. No specific paddling routes, water temperatures, water quality details, or on-site facilities for paddlers are provided.
