Kinnickinnic State Park is a 1,242-acre Wisconsin state park where the Kinnickinnic River, known locally as the Kinni, meets the St. Croix River. At the river’s mouth, the Kinnickinnic forms a sandy delta popular with boaters for picnicking and camping. The park is shaped by its river corridor, with Weymouth pine along the banks and trout in the river. Wildlife is central to the landscape, especially migrating birds, with more than 140 species recorded in the valley. Summer brings pheasants and grey partridges, winter brings bald eagles, and wild turkeys were reintroduced in 1989. The park is valued for its quiet scenery and seasonal wildlife.
