Rideau Canal.

The Rideau Canal in Ottawa, Ontario, is a UNESCO World Heritage Site with rich historical significance and year-round recreational activities. Originally built in the early 19th century for military defense, it remains the only operational North American canal from that era, showcasing its well-preserved structures. In winter, a 7.8 km stretch transforms into the world’s largest naturally frozen ice rink, the Rideau Canal Skateway, welcoming nearly a million visitors annually, 24/7. Beyond skating, the canal offers ice fishing, cross-country skiing, and snowshoeing in winter, while warmer months invite paddling and boating. Cultural events, especially during Winterlude, further enhance its charm, with amenities like skate rentals and food vendors enriching the experience.
