Boundary Waters Canoe Area Wilderness (1978) · Superior National Forest

The Kawishiwi is the most-traveled canoe route into the Boundary Waters Canoe Area Wilderness — over a million acres of roadless lake-and-river country straddling the Minnesota-Ontario border. Paddlers portage between crystal-clear lakes connected by short river segments through boreal forest unchanged since the last ice age. The classic entry runs from Kawishiwi Lake to the Sawbill Entry with an iconic 80-rod carry around Kawishiwi Falls.

Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
