Surrounded by Lake Superior, Isle Royale National Park encompasses 850 square miles of natural wilderness, spacious lands, and aquatic life.
A cool climate, crystal-clear waters, and the wild North Woods forest characterize Isle Royale National Park. The park encompasses a total area of 850 square miles including submerged lands which extend over four miles out into Lake Superior, and 99% of the land mass is federally designated wilderness. The archipelago is composed of numerous parallel ridges, the result of ancient lava flows which were tilted and glaciated.
Isle Royale has 165 miles of scenic hiking trails and 36 campgrounds for backpackers, paddlers, and recreational boaters. There is excellent fishing, historic lighthouses, and shipwrecks, ancient copper mining sites, and plenty of spots to observe wildlife. Isle Royale is accessible only by boat or float plane.
