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.
The difficulty of Gammon River River varies by section.
The best time is July–August.
Gammon River River is located in the Manitoba region of Canada.
