The Main River is home to one of the only known old-growth boreal forests in the world, and is one of the last wild areas in the province. The River hosts a rare population of Atlantic salmon, and is famed for its fly fishing. In its relatively short journey of only 57 kilometres, the Main passes through a variety of geography that is comparable to much longer rivers in other regions of Canada. It begins in the heart of the Long Range Mountains, courses through tundra-like barrens, forests, canyons and grasslands, then empties into the North Atlantic at the community of Sop's Arm. The Main is one of Newfoundland's great recreational resources.
