Why Visit Ottawa River

The **Ottawa River** is Canada's second-longest river and the chief tributary of the St. Lawrence, flowing 1,271 kilometers from the Abitibi-Témiscamingue wilderness in Quebec to Montreal[2][7]. Straddling the Ontario-Quebec border for most of its course, the river defines the region known as the **Ottawa Valley**—Canada's Whitewater Capital, renowned for glacially-carved landscapes, pristine waterways, and a distinctive blend of outdoor recreation with historic small-town character[1]. The valley's 200-kilometer recreational trail network and world-class whitewater rivers attract adventure seekers year-round, while its pivotal role in Canada's fur-trading and logging heritage infuses the region with cultural depth[1][3][7]. The river's most scenic reaches feature dramatic views of the Laurentian Mountains, accessible via canoe, kayak, houseboat, and hiking trails[3]. Visit May through September for peak outdoor season, though winter transforms the valley into a snowshoeing and cross-country skiing destination[1].
