Canada's water experiences are as varied as the country's geography, which is to say they cover an enormous range. The whale watching tours of British Columbia — humpback and orca sightings in Johnstone Strait and the waters around Vancouver Island — are among the finest in the world. St. Lawrence River cruises past the Charlevoix cliffs, sunset sailing on Lake Ontario, and sea kayaking through the Broken Group Islands on the Pacific coast each offer a completely different experience of a country whose coastline is the world's longest. In Quebec, river ferry crossings between Quebec City's upper and lower towns are themselves a scenic detour worth taking.
