Old Mill State Park
A log cabin and a steam-powered flour mill at Old Mill State Park are bold landmarks from the past. The grist mill still gets fired up once a year to grind flour.
The Middle River meanders through the park and visitors can see deer, beaver, and ruffed grouse. Enjoy the prairie and the ever-changing parade of wildflowers along wooded trails.
A swimming area, swinging bridge, picnic grounds, campground, and interpretive displays are popular among visitors.
