Isle Royale National Park Planning Guide & Strategy

Isle Royale National Park: pine forest and rocky shoreline along Lake Superior viewed from a high overlook.

Explore a rugged, isolated island far from our connected communities. Isle Royale offers adventures for backpackers, hikers, boaters, paddlers, and divers. Cross Lake Superior and make a commitment: Become a part of this island, and let it become a part of you. Find peace and refuge in island wilderness – because Isle Royale, in turn, finds refuge in us. Help Isle Royale stay wild.
