The Kettle Moraine State Forest is a state forest in southeastern Wisconsin. The chief feature of the reserve is the Kettle Moraine, a highly glaciated area. The area contains very hilly terrain and glacial landforms, such as kettles, kames and eskers. The 56,000-acre (23,000 ha)  forest is divided into two large and three small units, which are spread across a hundred miles.
The forest includes 250 miles (400 km) of hiking trails, almost 100 miles (160 km) of cross-country ski trails, 130 miles (210 km) of equestrian trails, 150 miles (240 km) of snowmobile trails, 75 miles (121 km) of off-road bicycle trails including 30 miles (48 km) of singletrack trail, and 750 campsites. 
All units include a portion of the Ice Age National Scenic Trail and most units have horse/snowmobile trails. Several areas of trail loops for hiking, biking and skiing can be found in the northern and southern units.
