In the far reaches of the Upper Midwest, an island vacation can mean youre heading north. Way north. Yes, there are islands in Wisconsin and Michigan, even some with sandy beaches. The sunsets are amazing. But dont expect any palm trees, and bring your rain gear. Like most islands, youll arrive by ferry or by air, but this isnt a boating magazine.Beaver Island, Michigan, the largest blob in a small archipelago, is 13 miles long and six miles wide. Its only 40 nm from the more-famous Mackinac Island. Youll want to spend some extra time planning the possible arrival routes-all of them-with the island sitting smack in the middle of upper Lake Michigan. Ignoring the water hazard, this scenic tour of northern Lake Michigan makes the perfect summertime trip. Just know that lake fog and cool, stratus-cloud days with rain are common up there even in the warmest months, so be prepared to file.
