Greenstone Ridge Trail, Hiking trail on Isle Royale National Park, Michigan, United States.
The Greenstone Ridge Trail stretches 40 miles from Windigo Harbor to Rock Harbor, following the natural spine of Isle Royale through dense forests and elevated ridges.
The establishment of Isle Royale National Park in 1940 designated this area as protected land, preserving its geological formations and natural ecosystems for future generations.
Native American communities utilized the resources of Isle Royale for generations, leaving archaeological evidence of their presence along what is now the Greenstone Ridge Trail.
Access to the trail requires transportation by boat or seaplane from departure points in Michigan or Minnesota, with services operating from Houghton, Copper Harbor, and Grand Portage.
The trail passes over Mount Desor, the highest point on Isle Royale, offering views of Lake Superior and inland forests while traversing multiple ecological zones.
