Please allow two hours to tour the Sanilac Petroglyphs.

Group tours are available by advance reservation. See a map of the site.
Pets: Pets accompanied by and under the control of their human friends are welcomed on the grounds of this site. Pets may not enter any building. For further information, please refer to the DNR web page, Pets in State Park Campgrounds.
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 for people with mobility impairments. Visitors will first encounter 12 feet of lawn and then reach the trail, which runs approximately 900 feet to the pavilion.
Thanks to a Thumb Area Boy Scout troop, two benches offer visitors a place to rest along the hiking trail.
