Sleeping Bear Dunes, MI :) - "Discovered" this beautiful site during our Great Lakes Vacation 2011. Unbelievable to find such fantastic landscapes in the heart of the Midwest along Lake Michigan's Eastern Shoreline, west of Traverse City.
Barnes County Park is just north of Elk Rapids and is a beautiful campground. It seems more rustic, but does offer electric hookup. The beach of Lake Michigan is spectacular too. I recommend visiting during Elk Rapid's Harbor Days in early August.
