Old Mill State Park 

Old Mill State Park is located in the Red River Valley region of northern Minnesota, near Thief River Falls and Newfolden.

How to Get to Old Mill State Park: Drive 11 miles west from Newfolden on County Road 4.

Park Highlights:

  • The history of the park is commemorated with landmarks like an old log cabin and a steam-powered flour mill. On Grinding Day, the last Sunday in August, the grist mill is put into operation to demonstrate its former use.

Old Mills State Park’s Natural Attractions:  

The Middle River meanders through the park. Walk above the river on the swinging stone bridge near the campground. Spring wildflowers add seasonal beauty near the river and in the woods.

Hiking the wooded trails may give you glimpses of the resident wildlife, including deer, beaver, raccoon, and ruffed grouse. During spring and fall migrations, the park is filled with birds like warblers and finches and, at times, magpies and scarlet tanagers. Eagles and several species of hawks and owls are often observed here as well.  

Things to Do in Old Mill State Park: Enjoy the swimming beach, picnic grounds, playground area, horseshoes, and volleyball. Interpretive displays and naturalist programs are offered during the spring and summer seasons. 

The 7 miles of hiking trails in the park include 1 mile of self-guided trail. In winter, there are 4 miles of cross-country ski trails, 1.5 miles of snowmobiling trails, and 2.5 miles of snowshoeing trails. A sliding hill and warming house with a wood stove add to the fun.

Camping in Old Mill State Park: There are 26 drive-in campsites for tents and RVs; 10 sites have electrical hookups. The one, tents-only, group campsite can accommodate up to 150 people.  Picnic tables, fire rings, showers, and flush toilets are available.
