The Gillette Visitor Center is located in P.J. Hoffmaster State Park, nestled among one of the nation’s most impressive dune systems. Perched at the top of a large sand dune, surrounded by a pristine wooded back dune, the center features exhibits that tell Michigan’s unique sand dune story. The half-mile Lake Michigan Trail, easily accessible from the visitor center, goes up and over the park’s sheltered back dune forest and leads visitors out into a grassy foredune with a sweeping view of the beach and Lake Michigan.back dune forest and leads visitors out into a grassy foredune with a sweeping view of the beach and Lake Michigan.
