Wild animals, pristine forests, crystal clear lakes and rugged shoreline are a few of Isle Royale National Park's many fine features. This island archipelago is 45 miles long and nine miles wide at it's widest point. The park encompasses a total area of 850 square miles including submerged lands which extends four and a half miles out into Lake Superior. Isle Royale has 165 miles of scenic hiking trails and 36 campgrounds for backpackers and recreational boaters. There is excellent Lake Superior fishing, historic lighthouses and shipwrecks, and plenty of spots to observe wildlife. Accessible only by boat or floatplane, Isle Royale is relatively untouched by direct outside influences and serves as a living laboratory and International Biosphere Reserve.
