Located about 2 hours from Ann Arbor, the Sanilac Petroglyphs, Michigan's only known prehistoric rock carvings attributed to Native American workmanship in the Lower Peninsula of Michigan, are on a 240 acre parcel historic site. The park contains a one mile hiking trail that crosses the Little Cass River in two places. The trail is open from 8 a.m. to 10 p.m. year-round. The Petroglyphs will be open for viewing Wednesday – Sunday, 10 a.m. to 5 p.m., Memorial Day through Labor Day (please call to confirm hours and dates). The archaeological site may also be available for a special viewing during the rest of the year via a Use Permit. Contact the park at 989-856-4411 and ask to speak to the park supervisor.
