Interstate State Park
RV Guide


Interstate State Park encompasses two adjacent state parks on the Minnesota-Wisconsin border, the larger one being in Wisconsin and the smaller one in Minnesota, which is how they got the name “Interstate”. However, there are separate entry systems for both parks. Wisconsin’s Interstate State Park is reputed as Wisconsin’s oldest state park established in 1900. Located on the picturesque location of the St. Croix River, Wisconsin’s Interstate Park features the exotic scenery of the Lake O’ the Dalles, the river of St Croix and its unusually striking gorges, and a variety of gorgeous hiking trails. The large forested regions feature eastern white pines, maples, and basswood, as well as wildlife including foxes, raccoons, white-tailed deer, river otters, minks, skunks, muskrats, beavers, and as many as 150 different kinds of birds. The best part is that you can see it all when you bring your RV.

The park comprises 1,330 acres containing different kinds of scenic vistas, the most popular of which is the Lake O’ the Dalles. Lake O’ the Dalles also features a swimming beach and provides recreation in the form of swimming, wading, boating, kayaking, canoeing, and fishing, so don’t forget to pack your swim suit and fishing supplies in your RV. Note-worthy natural attributes of the park include interesting rock formations on the Dalles of the St. Croix. This steep gorge has been carved into a figure of an old man known as the Old Man of the Dalles. Other prominent natural areas of the park include the Interstate Lowland Forest and Centennial Bedrock Glade. Since it first opened, the park’s Ice Age Interpretive Center has been a major hit among the visitors offering exhibits, murals, photographs, and short films about the Ice Age and its glacial characteristics. Open every day, the park welcomes visitors year-round. The peak season continues from spring to fall. The camping season also usually lasts for the peak season with most of the camping amenities and sometimes the entire campgrounds getting shut down in extreme winter. Typically, the camping section is divided into two campgrounds containing electric hookup sites, so you’ll be taken care of when you bring your RV to Interstate State Park.
