Horicon Marsh is one of those places that is genuinely difficult to prepare first-time visitors for. Covering over 32,000 acres, it is the largest freshwater cattail marsh in the United States — a nationally significant wetland that sits just twenty minutes from Beaver Dam and draws birdwatchers from across the country year after year.
In spring and autumn, the marsh becomes a staging ground for hundreds of thousands of Canada geese alongside a remarkable variety of migratory waterfowl. Sandhill cranes, great blue herons, white pelicans and bald eagles are regularly spotted here. Even outside migration season, the marsh holds a quiet, expansive beauty that rewards the short drive.
The National Wildlife Refuge section offers miles of walking trails through marsh and upland areas, along with a visitor centre with exhibits about the ecology and history of the site. Canoe and kayak launch points allow for a paddling route that puts you level with the waterline — a completely different perspective on the landscape.
Plan at least two to three hours if the weather is cooperating, and bring binoculars if you have them. Early morning visits during migration season are particularly rewarding. Admission to the refuge is free, and the drive through the area is scenic in its own right.
