The Interstate State Park, located on 295 acres in Taylors Falls, is the second-oldest state park in Minnesota. Created in 1895, its unique topography and geological history draw many visitors to the area. It is the first park in the United States to be located in two states, Minnesota and Wisconsin, with the St. Croix River serving as the border. The two parks are operated separately by the states’ Departments of Natural Resources.

Interstate Park comprises two adjacent state parks on the Minnesota–Wisconsin border, both named Interstate State Park. They straddle the Dalles of the St. Croix River, a deep basalt gorge with glacial potholes and other rock formations. The Wisconsin park is 1,330 acres (538 ha) and the Minnesota park is 298 acres (121 ha). The towns of Taylors Falls, Minnesota and St. Croix Falls, Wisconsin are adjacent to the park. Interstate Park is within the Saint Croix National Scenic Riverway and the Ice Age National Scientific Reserve. The western terminus of the Ice Age National Scenic Trail is on the Wisconsin side. On the Minnesota side, two areas contain National Park Service rustic style buildings and structures that are listed on the National Register of Historic Places.
