22811 Swan Lake Dr. Carroll. Big lake with reportedly with big fish. Boats available, small beach. Full service sites are 30 amp and a little tight with no grass. Many semi-isolated sites that are dry or tents are scattered among the hundreds of acres of well kept park. There is a bicycle path around the stocked 150+ acre lake. Buffalo and rescued Bald Eagles are on site along with a pair of Whooping Cranes, and a nature center. I would have given it a higher rating if not for the tightness of the full service area and lack of a camp store. Our 40 footer could have used a little more room and more amps. I would, however, stay here again. We camped here in a Motorhome.
