Greenstone Ridge Trail Professional Reviews and Guides
"Isle Royale National Park's most extensive trail, following the backbone of the main island. The "Greenstone," as it's called here, is rated by many as the best of the Isle Royale hikes.
The trail goes from Windigo, in the west, to Lookout Louise, in the east, traversing 40 miles of rugged beauty along the highest ridges of Isle Royale. Special attractions: Dense forest and rugged wilderness, occasional views of Lake Superior, Lake Desor, Hatchet Lake."
