Kettle Moraine State Forest, located in the southeastern part of Fond du Lac County, is a 10,582-acre portion of the 27,725-acre northern unit of Kettle Moraine State Forest.
Made up of geological formations caused by retreating glaciers, the forest is managed for forestry and outdoor recreation. Textbook examples of glacial landforms are scattered throughout the forest, such as drumlins, kames, eskers and kettles. Botanically, the forest is quite diversified with nearly sixty species of trees present, together with numerous shrubs, wild flowers, ferns and other plant life. There are nearly 40 mammal species ranging from the white-tailed deer to the small mammals. Birds are seen everywhere, especially during the spring and fall migrations. Some of the higher ridges and eskers provide excellent viewing areas.
The major recreational developments within the forest are located at Mauthe Lake south of New Prospect, and at Long Lake north of Dundee. Both have excellent camping and hiking facilities. Mauthe Lake offers electricity, trailer sites, tent camping, fireplaces, picnic tables, sanitary facilities and drinking water, while Long Lake offers all of the above except electricity. Hiking trails and cross-country ski trails are available in several parts of the Kettle Moraine.For more information go to the Wisconsin Department of Natural Resources website.
