Breakfast with the walruses, lunch (carefully) with the polar bears, and spend the afternoon watching the seals do their tricks. When you tire of the mammals, check out the thousands of species of fresh- and saltwater fish in the aquarium's massive, three-level aquatic gallery, or have some hands-on experiences with mollusks, starfish, and stingrays. Don't miss the jellyfish ballet or seahorse tanks in the new pavilion. It is the only aquarium in North America with examples of all five species of cold-water seals. The aquarium is on a cliff top overlooking the St. Lawrence and Québec City's two main bridges.
