McMillan Marsh The McMillan Marsh Wildlife Area (MMWA) is a green oasis which lies to the immediate north/northwest of Marshfield. This area is felt to be an invaluable “recreational asset” and “environmental safeguard” to the citizens of Central Wisconsin.

Because northwest winds pre-dominate the area, this green space along with the farms northwest of Marshfield, ensures the city is constantly bathed with clean air.

The filtering and purifying value of the wetlands also contributes significantly to clean surface and drinking water.

The MMWA provides quality and varied recreational opportunities to the citizens of Wisconsin. It’s a great place to hike, watch birds, snowmobile, hunt, trap, bike, photograph or just walk the dog.

What to do at the Marsh:

  • Walking your dog (Dogs must be on a leash April 15 thru July 31 for the protection of ground nesting wildlife)
