If you have never visited the Pictured Rocks National Lakeshore near Munising in Michigan's Upper Peninsula, this article in the Mining Journal might convince you to head north. I have hiked the Pictured Rocks area (nothing too rugged) but have not had the pleasure of viewing the impressive rock formations and waterfalls from a boat. According to the article, viewing the Pictured Rocks from a boat is the best way to go as far as what you get to see. I would love to take a Pictured Rocks Cruise sometime as well as take a shipwreck tour from a glass bottom boat via Shipwreck Tours which is also based out of Munising.
