About

The Coulonge River is one of Quebec's legendary 'Three Sisters' offering 125-240 km of spectacular whitewater through pristine wilderness. With 64 rapids ranging from Class I-IV, 16 portages, and 34 campsites, it provides the most diverse geography of the three sisters - from Canadian Shield bedrock to sandy esker meanders. The river features excellent sandy beach campsites, rock-studded runnable rapids, and scenic waterfalls like Chute Gauthier. Starting from Lac Pomponne, paddlers experience 8-10 days of world-class whitewater with excellent access and shuttle services, making it ideal for intermediate to advanced canoeists.

This table publishes no position for any rapid. Where a surveyor's note mentions a kilometre, those are their words quoted as written, and the figure was read off a scanned map: use it to follow their description, not to navigate. Most of these surveys were written in French.
