It is positioned approximately 4 kilometers south of the Roxboro neighborhood on the Island of Montreal and is noted for being roughly a 30 to 45-minute drive from downtown Montreal. The beach provides direct shore access for launching paddlecraft like kayaks and stand-up paddleboards. The overall character is that of an urban beach, popular for summer recreation and offering views of the river and the nearby Île Bigras. The immediate area includes Parc Gouin and is within proximity to the Île-Bigras REM station, located about 3.5 kilometers to the west.
