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.

We will not be grooming ski trails at Old Mill State Park, but you may ski, snowshoe or hike anywhere in the park except on trails groomed for snowmobiling. Closest State Park with groomed ski trails is Lake Bemidji State Park.
