The Gammon River is a remote northern Manitoba wilderness route flowing approximately 280 km northeast through pristine boreal forest and tundra transition to Hudson Bay's Churchill River system, offering expedition-level paddling for experienced canoeists. This Class I–II rapid route features excellent wildlife habitat (moose, caribou, occasional polar bears), clear-water sections, and minimal human presence, with camping only at primitive or self-managed sites. Best paddled July–August when Arctic water levels permit passage; access requires air charter to remote put-in points and coordination with local guides. The Gammon demands expedition experience, advanced whitewater reading, and self-sufficiency in one of Canada's most remote regions.
Gammon River is estimated at Intermediate. Whitewater ratings are not exact: grades change with water level and season. Verify current conditions locally before you paddle.
The best time is July–August.
Gammon River is located in the Manitoba region of Canada.
