Fodor's Expert Review William O'Brien State Park

Located 12 miles north of Stillwater, along the banks of the scenic St. Croix River, this 2,200-acre state park is paradise for outdoor adventurers and nature lovers alike—hiking, bicycling, cross-country skiing, and swimming are all available and the river's channels are stocked with walleye, bass, and trout. Canoes can be rented from mid-April to late October. In addition to a 112-site campground, three cabins offer electricity and overnight camping from April to October. There is also a year-round cabin.
