Interstate State Park

A steep-sided gorge called the "Dalles of the St. Croix" is the scenic focus of Wisconsin's oldest state park. The park's Ice Age Interpretive Center features a 20-minute film, photographs, murals and other information about the great glaciers. Three state natural areas are contained within the park's 1,400 acres protecting unique glacial features and plant communities. Habitat types include upland and lowland forest, and bedrock glade. The park contains numerous wetland areas and encircles Lake O' the Dalles. Winter Recreation Trails are multi-use trails and are open to snowshoeing, hiking, pets and cross country skiing. Snowshoers, hikers and pets are not allowed on the Skyline Trail when groomed.
