Hartwick Pines State Park protects one of the Lower Peninsula’s best-known remaining stands of old-growth pine. The visitor center at 2833 Monarch Drive in Grayling introduces the forest’s ecology and Michigan’s logging history before visitors head onto the Old-Growth Forest Trail and the museum complex.
Visitor Center and Old-Growth Trail
The visitor center’s exhibits cover Michigan forests from the Ice Age and historic logging era through modern forest management. From the building, the paved Old-Growth Forest Trail leads into the towering pine stand. The route is accessible but includes two steep grades, so visitors using mobility devices should review conditions or ask staff about available assistance.
Hartwick Pines also offers a free track chair for the Old-Growth Forest Trail and hunting areas. It is generally available daily May 1–Nov. 30 from 9 a.m.–3 p.m.; call 989-348-7068 at least 24 hours ahead when possible.
Logging Museum
The Michigan Forest Visitor Center and the Hartwick Pines Logging Museum serve related but different purposes. The museum complex interprets the state’s 19th-century lumber era through historic-style camp buildings and equipment. Its schedule is shorter than the visitor center’s, so do not assume both are open.

Practical Tips
Wear footwear suited to roots, needles and wet pavement; keep dogs leashed; and stay on established routes around the old-growth stand. The forest—not a single landmark—is the main attraction, and even a short walk from the visitor center provides the park’s defining experience.
