[1][2] The Northwest Miramichi River has its origins near Big Bald Mountain in the Miramichi Highlands, part of the Appalachian Mountains in Northumberland County.
It continues south to Sunny Corner where it becomes tidal, and then flows east.
The headwaters offer important spawning sites for Atlantic Salmon; thus, much of the upper river is either closed to fishing, or designated as Crown Reserve and subject to special fishing regulations.
In spring canoeists often run the lower stretch of the river from Miner's Bridge (where the river first crosses Route 430), south to Redbank and Sunny Corner.
