Wisconsin

Marathon County sits in the heart of Wisconsin, covering a large portion of the state’s northern half. As Wisconsin’s largest county by land area, it offers plenty of room for forests, farms, communities, and outdoor recreation.

Wausau is the county seat and urban center of the area. However, much of Marathon County has the classic feel of Wisconsin’s Northwoods, with Rib Mountain standing out as a popular destination for skiing, hiking, and other outdoor activities.

Ginseng is an important part of the local agricultural economy, with the county producing a significant share of the nation’s crop. Granite quarries have also shaped the area’s history and can be seen in historic buildings throughout downtown Wausau. With industry, agriculture, and wilderness all in one place, Marathon County offers a unique blend of hardworking communities and natural beauty—pure Wisconsin.
