A great "get away" park only one hour from the Twin Cities, William O'Brien provides a beautiful setting for quality recreation along the banks of the St. Croix River. 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. In the winter, snowshoeing, skiing and camping attract enthusiasts.
