The Maligne River flows through the heart of Jasper National Park in Alberta, Canada, offering one of the most scenic and rewarding fly fishing experiences in the Canadian Rockies. Originating from the outlet of the renowned Maligne Lake, the river winds through dramatic mountain terrain before passing through the spectacular Maligne Canyon and eventually connecting with Medicine Lake. This is a river where wild trout hold in crystal-clear mountain water against a backdrop of towering peaks and old-growth forest — a setting that makes every cast feel like a privilege. The river serves as a critical hatchery corridor for both Maligne Lake and Medicine Lake, which shapes its regulations and makes it a particularly productive and ecologically significant fishery.
