Sanilac Petroglyphs Historic State Park

Sanilac Petroglyphs Historic State Park protects and interprets Michigan’s largest known collection of early Native American teachings carved in stone. The carvings are called Ezhibiigaadek Asin, “written on stone,” in the Anishinaabemowin language.

Please note that the trail along the river floods often - it may be muddy or even impassable at times. Get tips on how to Recreate Responsibly in these conditions.

The petroglyphs are open to visitation Wednesday through Sunday from Memorial Day through Labor Day.

Admission to the petroglyphs is free; a Michigan State Parks Recreation Passport is not required for entry to either the park or the historic site.
