@dadssecretacct the village of Esterel, and its surroundings in the Laurentians, is known for its lakes (summer cabins). Same thing for the village of Sutton and Magog in the Eastern Townships.
@dadssecretacct If you're in the Quebec City area and willing to take a 2-day close to the city, I'd recommend La Malbaie (with the Manoir Richelieu, the Casino, the little village).
Near Montreal, there's Oka Beach (which has a nude gay section).
