The park is home to a rare prairie remnant that has been actively restored by the Department of Natural Resources.
The sandy delta at the river mouth was formed by sediment deposits from the Kinnickinnic River as it enters the St. Croix.
The St. Croix River, which borders the park, is designated as a National Scenic Riverway.
The Kinnickinnic River is a Class I trout stream, signifying it supports a naturally reproducing population of trout.
Kinnickinnic State Park is situated at the confluence of the Kinnickinnic and St. Croix Rivers, featuring a unique delta formation. The park encompasses over 1,200 acres of bluffs, prairies, and forest environments. Visitors have access to a sandy beach located along the St. Croix River, which is a popular destination for swimming and sunbathing. The trail system spans approximately 6 miles, traversing wooded ravines and open grasslands. Anglers frequently target the Kinnickinnic River for its trout fishing opportunities. The park includes a designated boat landing providing access to the St. Croix National Scenic Riverway. A significant portion of the landscape consists of restored oak savanna and prairie habitats. Wildlife viewing includes species such as white-tailed deer, wild turkeys, and various raptors. The park is managed by the Wisconsin Department of Natural Resources.
