Witness the grace of the largest underwater mammals and the fragility of our ecosystems. In Tadoussac, the massive forms of these graceful mammals glide effortlessly just beneath the water’s surface of the St-Lawrence River. The song of the whales echoes eerily against the cliffs. From the deck of the cruise ship feel the spray when they blow and dive. The unique Marine Mammal Interpretation Centre displays the fascinating and mysterious world of whales. A lifetime thrill!
