We are looking to tour round one or more of the great lakes. I am finding it a bit hard to get an idea of how far it would be. I was looking at driving around Lake Superior but there does not seem to be an international airport close enough and we do not like to change flights. Is there enough to do for 2 weeks driving round Lake Michigan? starting and finishing in Chicago? Or is there more lake area that could be added to make a full trip? We like to drive 150 - 300 miles between stops and stay for one/two or three nights each stop depending on how much there is to see. We like scenery, waterfalls, hiking a bit (or just walking), little towns to explore, boat tours etc.
