Isle Royale National Park
A remote Lake Superior archipelago protects boreal forest, ridges, inland lakes, shipwrecks, moose, wolves, and long backpacking and paddling routes reached only by boat or seaplane.

Isolation is the defining resource and the central logistical fact. Predator-prey research is famous, but weather, fire, disease, shoreline ecology, mining traces, and Anishinaabe relationships make the island more than a wolf-and-moose laboratory.
Plan transport and permits before choosing trails; ferry schedules, wind, fog, cold water, insects, and limited services control every itinerary. Day trips reveal only a narrow edge, while backcountry travel requires self-rescue judgment and food protection.
