Located on the shores of a bay protected by the seven islands that gave it its name, the municipality of Sept-Îles boasts a splendid archipelago in the heart of a region recognized as one of the five best places in the world to observe and follow whales. A sea excursion in this archipelago offers you front-row seats to a unique nature show, with the blue sea and sky as backdrop, the cries of the seabirds as musical accompaniment, and magnificent sunsets to add to the magic of the experience.
Each of the archipelago’s islands has distinctive features. Corossol Island is a bird sanctuary and a perfect place for whale watching. Blue mussels are cultivated near Grosse Boule Island. Grande Basque Island is the only island with hiking trails and campsites; you can also participate in interpretive activities with naturalist guides that focus on the marine environment. You can also explore the archipelago by Zodiac or sea kayak. Finally, this is an exceptional site for scuba diving. Explore three nearby wrecks: Le Corossol, the Jean-Marc Soucy and the St. Olaf.
