Isle Royale National Park

If traveling through Grand Portage, the Boundary Waters Canoe Area of Minnesota and Quetico Provincial Park of Ontario provide a paddling paradise to the west. Houghton-Hancock and Copper Harbor are located on the scenic Keweenaw Peninsula Isle Royale's geological sibling, and it's not far from there to Pictured Rocks National Lakeshore, another nice hiking area to the southeast.
