Greenstone Ridge Trail, Isle Royale National Park, Michigan, USA
Isle Royale can only be reached by boat, guaranteeing solitude on this remote 42-mile trail that spans the island. You’ll be immersed in boreal forest home to moose and wolves, occasionally topping a bald ridge offering views of the island and Lake Superior.
