North of U.S. Highway 12 on Broadway Avenue, Beverly Shores, IN 46301

A really nice birding hike with views of the largest wetland complex in the Lake Michigan watershed. Flocks of coots, mallards, and wood ducks now glide over the wetland's surface. Kingfishers, tree swallows, and rusty blackbirds rest during migration. Green herons stalk the shoreline while beaver play in the channels. The Great Marsh abounds in the diverse animal activity of a healthy wetland ecosystem. During the migration periods, the wetland will be frequented by flocks of ducks and geese. The wading birds like herons and egrets, and the song birds such as warblers and red-winged black birds are abundant.
