Greenstone Ridge Trail, Houghton Township, MI, Stati Uniti
Isle Royal National Park is unique in that the entire preserve exists on an isolated island in the middle of Lake Superior in Michigan. Just to get there, hikers must first catch a daily ferry that can carry them to the start of the 40-mile long Greenstone Ridge Trail, which runs west to east through the wild center of the island. Surprisingly, there is plenty of wildlife to spot on Isle Royal, including moose, deer, and wolves. The trek is a scenic one too, often offering prime views of the Lake Superior shoreline along the way. This is a spectacular walk through a national park that most people don't even know exists.
