Isle Royale is the largest island in Michigan's Lake Superior. It is a little more than 45 miles in length, and 9 miles wide. Interestingly, the park is composed of Isle Royale plus 400 smaller islands. Isle Royale was established as a National Park in 1940. At one time, indigenous people mined copper there, and on it's close neighbor, the Keweenaw Peninsula. Ancient copper mine pits and trenches have been discovered on Isle Royale, that are believed to be 5,700 years old.
These ancient copper mine trenches lead to another period of copper mining exploration, during the 1800's. Lighthouses guided ships thru the islands, at Passage Island, Rock Harbor, Rock of Ages, and at Isle Royale. For those of you who like to study shipwrecks, the deep water shipping routes near Isle Royale contain a number of historic shipwrecks. The Greenstone Ridge runs thru the middle of the island, and it's a great place to hike the longest trail in the park, Greenstone Ridge Trail. This trail runs about forty miles, from one end the island to the other. It's a nice four or five day hike, and a boat shuttle will carry you back to your starting port. There are one hundred sixty-five miles of hiking trails, for your enjoyment on Isle Royale.
If you favor wilderness camping, Isle Royale has thirty-six designated places for you to enjoy wilderness camping at its' best. Some of the campgrounds are accessible by trail, canoe, or kayak.

You may see wolves or moose, on the island. In fact, it is the only known place where wolves and moose live side by side without bears.
