While visiting the park, stop by the Philip A. Hart Visitor Center in Empire, the Dune Center Bookstore at the Dune Climb, or the Glen Haven General Store to get your copy of the Junior Ranger Workbook. The books are FREE! Complete the challenges in the workbook and return to the Philip A. Hart Visitor Center for a Ranger to check over with you, so you can receive the Sleeping Bear Dunes Jr. Ranger Badge or Patch.
