Old Mill State Park Campground

9 ReviewsAdd Review

With 27 sites accommodating RVs up to 67 feet, Old Mill State Park Campground operates seasonally from late May through October in northwestern Minnesota. The DNR-managed facility charges $20-30 per night and accepts reservations for sites featuring electric hookups on the inner loop, while water access remains available throughout the campground.

The compact layout includes clean restroom facilities with showers, and campers consistently note the well-maintained grounds. Multiple hiking trails wind through the park, though seasonal flooding can affect accessibility on some routes. Wildlife viewing opportunities abound along the prairie trail system, where visitors spot butterflies, frogs, and chipmunks among the native vegetation. Wild raspberries grow along certain trail sections during summer months. A sandy beach area provides swimming access to the Middle River, though water levels fluctuate seasonally.

Historical attractions include a restored grist mill and settler's cabin that draw day visitors to explore the area's milling heritage. The campground's self-serve firewood station operates within the camping area. "LOTS of mosquitos when we visited - bring bug spray & extra bug spray!" advises Ason S.. Sites spread across open terrain with adequate spacing between neighbors.

Book early for summer weekends, as this smaller state park fills quickly despite its modest size.

Visitors often highlighted this small, well-maintained campground's clean facilities, nicely spaced sites, and peaceful atmosphere. Many mentioned excellent trails, wildlife viewing, and a beautiful swimming beach, though mosquitos can be heavy during certain seasons.

Nice little park with more then expected

The campground is tiny but there are showers, bathrooms and water readily available and I think it is a lightly used park. Good trails, nice exhibits and a surprising amount of wildlife. The river was very high and overall very wet summer so far but green.

Small park and campground

This park and campground are both pretty small but still a great stay! I was here early in the season...a lot of the trails had flooding. The hiking club trail was particularly bad as a good portion was at least ankle deep. My dog had to be carried so I wasn't able to get pictures of that 🤣

Worth checking out; bring bug spray

Nice little campgrounds. Our favorite part was checking out the Old Mill & settler’s cabin. Unfortunately, the bridge & swimming pond were closed. Electric & water hook ups on the inner loop. LOTS of mosquitos when we visited - bring bug spray & extra bug spray! Great little self serve firewood spot in the campsite. Kept clean. Trails were neat, but we spent minimal time on them due to the bugs. Playground is a swing set.

Fab HC Trail in July!

Park is on the smaller side compared to other state parks but was great with a very nice beach. Scenic prairie trail with tons of wild life to watch like butterflies, frogs, chipmunks, grasshoppers, and caterpillars. Wild Raspberries grow along the trail as well.

Nice area and historical

This was a really cool park to go to, there’s a couple historical building for those interested in history and mills. Many trails to walk on and there’s a beach area for those who like to swim. Campsites are nicely spread out and everyone is friendly.

A Park with Quiet Beauty

While this park isn't a take your breath away experience, it is a solid park for hiking and solitude. We went in fall so we didn't get to enjoy but there was a beautiful sand beach to swim at that would be perfect in the summer time.
