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.

The park includes the petroglyphs and a mile-long, self-guided walking trail featuring peaceful forests, the remains of a 19th-century logging camp and a 110-year-old white pine.

The Sanilac Petroglyphs Historic State Park is co-managed by the Michigan Department of Natural Resources Parks and Recreation Division, the Michigan History Center and the Saginaw Chippewa Indian Tribe of Michigan.

Sanilac Petroglyphs Historic State Park is open year-round. The enclosure that protects the petroglyphs typically open Memorial Weekend until around Labor Day Weekend (end of May until beginning of September)

Accessibility
A spaciously wide layer of crushed limestone on the trail connecting the parking lot and the archaeological site has the feel and functionality of concrete, providing greater accessibility. Visitors will first encounter 12 feet of lawn and then reach the trail, which runs approximately 900 feet to the pavilion.
