Our next stop is Grand Marais, Minnesota, our base to visit Isle Royale National Park. Isle Royale is an island in the middle of Lake Superior. The park, famous for its moose and wolves, is one of the least visited national parks. It is only open from April to November and… it is only accessible by boat or plane. Another boat trip, this was now our fifth in a little over two weeks. We were really done boating. But it had to be done – we couldn’t miss the National Park… and a seaplane is not in the budget.
