A Wild, Isolated Island


Isle Royale National Park is a rich historical location, settled by native American copper miners long before the days of Christopher Columbus. In the late 1800's, it became the home of numerous commercial fishing families, many of whom were Scandinavian and German immigrants. 

Isle Royale National Park, extending over 50 miles, is the "eye" of Lake Superior. The main island is 45 miles long and 8 miles wide, covering over 571,790 acres, most of which is back country wilderness. Isle Royale National Park was authorized in 1931, and in 1980 was designated a biosphere reserve. It is currently home to an amazing abundance of wildlife, including wolves, moose, fox, beaver, gulls, cormorants, loons, ducks, otters, eagles and rare plants.







A Northland Family Legacy


Grand Portage Isle Royale Transportation Lines began as a way for the Sivertson family of Lake Superior's north shore to transport their catch of freshwater fish from Isle Royale to Minnesota. It gradually expanded to include passenger service. 

Today, "GPIR" provides transportation for adventurers who wish to camp, hike, canoe or kayak throughout the park, as well as those who only wish to enjoy the park's natural beauty and history for the day.
