[1] It empties into the north shore of Lake Superior east of Terrace Bay.

From here the Steel River turns 180 degrees, flowing due south to Lake Superior.

It is a free flowing river with steep canyons and rugged bedrock terrain.

It was first advertised as a canoeing destination in the 1890s by the Canadian Pacific Railway, that crosses the river near its mouth.

It was established in 1989 to protect the cultural and natural features of the river, while also providing backcountry recreational opportunities.
