Hartwick Pines State Park contains one of the few surviving stands of virgin white pine forest in the Midwest.  Trails lead visitors through the forests to the 300 year old Monarch Pine, a momument to the forests that no longer exist today.
 

    Another attraction is the Hartwick Pines Lumbering Museum.  The museum contains exhibits featuring the 19th century Michigan lumbering opertations.  At that time, Michigan led the nation production of sawed lumber.  The Visitor's Center, replicas of lumber-camp buildings, and outdoor exhibits tell the story of Michigan's lumbering history.
