AAA Editor Notes
Horicon Marsh, 3 mi. e. on SR 49, occupies 33,000 acres of wetlands and uplands. During the annual spring and fall migrations more than one million Canada geese travel through the marsh. As many as 200,000 geese can be seen at a time along with many other bird species who use the marsh as a stopover. Mallards, redheads, ruddy ducks and blue-wing teals nest during the summer; egrets, herons, muskrats and deer also are common. Observation areas off SR 49 and Rockvale Road provide optimal viewing.
A self-guiding auto tour winds through 3.2 miles of the national refuge; three hiking trails and a floating boardwalk are accessible from the route. Maps are available at the refuge visitor center, W4279 Headquarters Rd. in Mayville.
The 34-mile Wild Goose State Trail runs from Fond du Lac to SR 60 south of Juneau, bordering the west side of Horicon Marsh. The Horicon Marsh Parkway makes a 30-mile loop of the entire Horicon Marsh and offers numerous overlooks; follow the signs from Horicon.
The northern 22,000 acres of the marsh, accessible from SR 49, are a national wildlife refuge; the southern third, accessible from SR 28 at Horicon, is state-owned.
