Cylon Marsh is a 513-acre site leased by the DNR. It is located on the northern end of Cylon Wildlife Area, a 2,345-acre property. The combination of the two provides marsh, old fields, woodlands and wetlands for a good variety of wildlife. Woodcock can be observed during their courtship flights in the spring. Ruffed Grouse, pheasants and a variety of waterfowl can also be found here. Birding along the trails will produce Song Sparrows, Eastern Kingbirds and Willow Flycatchers. Abundant wild berries grow here.
