Photo of Isle Royale National Park. "Isle Royale’s physical isolation and primitive wilderness challenged human use for centuries; ironically today it has become the Island’s main attraction. Accessible only by boat or seaplane, visitors come to experience this island park through hiking its trails, paddling its inland waterways, exploring its rugged coast, or venturing into the depth of its shipwrecks."
