The eternal wave, nicknamed “Vague à Guy” (Guy’s Wave) is located in the St. Lawrence River near the Parc des Rapides. It is an excellent site for surfing, kayaking and paddleboarding. Here is what you need to know before going there.

A place for enthusiasts in the know

The city does not supervise this area and cannot be held responsible for any accidents. Guy’s Wave is not for everyone. It is strongly recommended that you go with someone experienced, or to take an introductory river surfing course at a recognized school before trying out the wave.

Heavy rains may affect water quality. Always pay attention to the signs.

Guy’s Wave is accessible to the public from May 1 to October 15 only. Nautical activities are not permitted there in the off-season.

Did you know that…

The eternal waves are created by the particular rocky relief of the St. Lawrence River bottom. They allow surfers and kayakers to stay in one place on the water.‌ ‌ 

Water Access Improvements

To limit the impact of visitors on the environment and to provide safe access, the city has built paths to the water. The goal is to direct visitor traffic and protect the shoreline, which has become fragile over the years. Nearly 150 metres of shoreline were also stabilized and naturalized to combat erosion.
