About
William O’Brien State Park sits on the beautiful St. Croix River and is the perfect getaway to enjoy the outdoors. Hiking trails offer quiet exploration of the park's rolling, wooded hills. For anglers, the channels of the St. Croix have northerns, walleye, bass and trout. Ideal for canoeing, the river is also a migratory pathway that offers visitors an exciting diversity of sights and sounds. There are plenty of opportunities to stay overnight, with 124 campsites, 4 group camps, and 4 camper cabins. In the winter, the trails are groomed for skiing and snowshoers can explore the Riverside Trail.
