When is the best time to watch the migration at Horicon Marsh?What are the best days to watch birds migrating at the Horicon Marsh? What is the closest town to the marsh? - Joane, Sycamore, Ill.
September and October are the best times to see thousands of ducks and Canada geese stop in this Wisconsin marsh on their way south, and May is the best time to watch the northward migration.
Horicon Marsh is the largest freshwater cattail marsh in the United States. Part of it is a national wildlife refuge and part is a state wildlife area.
If you like festivals as well as bird-watching, go the first weekend of October for Audubon Days in Mayville, which includes a big parade at noon Sunday.
But you can see birds any day: by canoe or pontoon boat from Blue Heron Landing or the two-mile Horicon Habitat Trail, both on the southern tip of the marsh in Horicon; from bicycle on the Wild Goose State Trail, along the western edge of the marsh; or from the 50-mile auto route around it.
The marsh is less than half an hour south of Fond du Lac, and the northern part is just two miles from Waupun. But the DNR office is in Horicon, on the south edge, and the national wildlife refuge visitors center is in Mayville, on the southeast edge.
