The Greenstone Ridge Trail is a 40-mile-long (64 km) hiking trail on Isle Royale, in Lake Superior, northern Michigan. The island is within Isle Royale National Park.
There are no roads on the island, a wilderness area and national park, so the trail doubles as the primary means of land transportation across the island. [1][2]
