Start with a trip to the Visitor Center in Empire, Mich. to get oriented and watch an introductory movie. Here, you can learn about the park’s natural history, get recommendations for the best trails and learn about the piping plover, an endangered species that’s protected. Ask about a Junior Ranger Program booklet to get kids engaged in the park’s displays and top attractions on dunes, lighthouses and Lake Michigan. They can earn a free Junior Ranger badge (and bragging rights) for completing a workbook.
