Take a day for Three Island Park.

Woods, trails, and the Turtle River

Three Island County Park covers 2,915 acres where Three Island Lake meets the Turtle River. It’s a day-use park north of Bemidji, with trails, picnic areas, and public boat access. Use Beltrami County’s park page for the official map and current visitor information.

Build the day around your group: a short walk and lunch outside, a longer route through the woods, or time on the water with your own equipment.

Choose your day

• Walking and sightseeing: pick a route from the park’s summer trail map.
• Picnicking: plan a stop near the shelter area. Contact the county if you need to reserve the shelter.
• Getting on the water: the public boat access serves Three Island Lake.
• Winter trails: use the winter map to find the routes designated for your activity.

The park is open sunrise to sunset. Check the county’s seasonal rules, dog access, and trail notices when planning your visit; permitted uses differ between trails.

Before leaving Grant Haven

Choose your trailhead on the county map and use current directions from the campground. Pack water, food, layers, and insect protection for the conditions. Save the map before leaving, and carry your rubbish out with you.

If you’re hoping for a particular trail surface, shelter, or launch arrangement, check those details with the park before you go. Leaving a little flexibility in the day makes it easier to adjust to weather.
