The State of Michigan is blessed with the riches of unspoiled nature: the nation's longest freshwater coastline, lakes that feel like oceans, golden beaches, an abundance of fresh produce straight from the farm, glorious sunrises and sunsets and endless opportunities for recreation. Here you will find more than 100 public beaches, some of the highest freshwater sand dunes in the world, stunning multi-colored sandstone cliffs, two National Lakeshores and the only national marine sanctuary in the Great Lakes--the Thunder Bay National Marine Sanctuary in Lake Huron. Along the shoreline discover 129 lighthouses, numerous maritime museums, ten shipwreck-diving preserves and historic military fortifications.
