Rideau Canal – UNESCO World Heritage Site
Built during a time when Canada feared a potential attack from the United States, the Rideau Canal has become a defining landmark in Ottawa. The 202-kilometre (126-mile) canal, which travels south to Lake Ontario, first opened in 1832. Its 47 locks and interconnectedness with lakes and rivers is a true engineering marvel, leading to its designation as a National Historic Site of Canada and a UNESCO World Heritage Site. Parks and trails line the Canal as its travels through Ottawa, perfect for a scenic picnic and bike ride.From May to early October the Canal becomes a popular spot for cruises, canoes, and kayaks. And during the winter it turns into the Rideau Canal Skateway, the world’s largest naturally frozen skating rink.
