Eldorado Wildlife Area is a 6,381-acre property located in central Fond du Lac County, just north of Hwy 23, and only 5 miles west of the city of Fond du Lac. 

The wildlife area consists of a rich mosaic of wetlands, small oak openings, shrubs, and grasslands. The West Branch of the Fond du Lac River flows through the wildlife area. The property is popular with waterfowl, pheasant, and deer hunters.

The dike and access lanes provide a 1 ¼ mile-long gravel surface excellent for wildlife viewing, especially during spring and fall migration and are commonly utilized by walkers, birders and nature enthusiasts.
