Seagull Bar State Natural Area

Seagull Bar is a sand spit and marsh complex on Green Bay. The sand spit shelters a lagoon and large area of shallow water with emergent vegetation. This area is the only dune complex with a system of sand ridges and wetlands on Green Bay. The area is a prominent bird migration stopping point on Green Bay. During some spring and fall migrations, shorebirds by the thousands gather there to rest and feed. The lagoon is attractive to all species of waterfowl.

Directions: Via Leonard Street in the southeastern corner of the city of Marinette, drive to Red Arrow Park on the shore of Green Bay. Walk southeast into the natural area. The park’s boat launch affords water access.
