Isle Royale National Park was authorized by Congress on March 3, 1931, by President Herbert Hoover. Isle Royale National Park was established on April 3, 1940, by President Franklin D. Roosevelt. The park was designated part of the National Wilderness Preservation System in 1976, under the Wilderness Act, and remains today as an example of primitive America.
The Park, located in Lake Superior’s northwest corner is a wilderness archipelago – a roadless land of wild creatures, unspoiled forests, refreshing lakes, and rugged, scenic shores – accessible only by boat or floatplane. Travel on and around the island by foot, boat, or float plane. Isle Royale has 165 miles of scenic hiking trails ready for exploration and 36 campgrounds for backpackers and recreational boaters. Excellent fishing opportunities abound on one of the Island’s many inland lakes or on Lake Superior.
