The Saguenay–St. Lawrence Marine Park is a National Marine Conservation Area, one of three in the Canadian national park system, located where the Saguenay River meets the Saint Lawrence River. It is the first national park in Québec to protect a purely marine environment. Whales are drawn to the rich food supply stirred up by the mixing of waters here, including a colony of belugas. This is a popular whale watching location, with a number of operators in the region.
This park is managed jointly managed by Parks Canada and Sépaq.
