Interstate State Park is located on the beautiful St. Croix River and offers several different adventure opportunities. You can climb the cliffs of the St. Croix River Dalles, watch kayakers rush through the rapids, canoe the flat-water, or take this hiking adventure. In the spring there are a diversity of wildflowers and in fall, the St. Croix River Valley forest displays brilliant autumn colors of gold, brown, red and orange. The hiking trails explore the glacial potholes that give this park its uniqueness.
