The Boundary Waters is a region of wilderness and semi-wilderness lakes, rivers, and forests straddling the border between Minnesota (USA) and Ontario, Canada. The Boundary Waters is often used within the U.S. to refer to the wilderness area protecting its southern extent, the Boundary Waters Canoe Area Wilderness. This region is part of the Superior National Forest in northeastern Minnesota, and in Canada it includes La Verendrye and Quetico Provincial Parks in Ontario. Voyageurs National Park (USA) may also be considered part of the Boundary Waters.
