The Marsh Haven entrance, on the north side of State Hwy 49

Marsh Haven Nature Center is located on the north end of the Horicon Marsh, just three miles east of Waupun, Wisconsin on State Road 49.

Marsh Haven Nature Center is separate from the Federal Refuge and the State Wildlife area, and is nestled on 46 acres just outside of the Horicon National Wildlife Refuge boundary.
