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 1330acre and the Minnesota park is 298acre. 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.Use our Taylors Falls trip planner to arrange your visit to Interstate State Park and other attractions in Taylors Falls.
1.1 billion years ago, a series of volcanic eruptions from the Midcontinent Rift System sent at least ten separate lava flows across the region that now includes Interstate Park. These flows hardened into basalt, which fractured at several joints. In the Cambrian period, between 530 and 470 million years ago, the region was covered by a shallow sea which deposited sandstone and siltstone atop the basalt. This epoch of the Cambrian, the Furongian, was originally called the Croixian in North America because the layers exposed in this area were its type locality.

We visited on the Wisconsin side and hiked Pothole Trail. It was a little challenging for seniors but were rewarded with beautiful views of the river below us. more »
I have been coming to Interstate for the last 25 years. I have always been impressed by both the MN and WI sides. The sites are beautiful, clean and easily accessible. Whether it's huge group sites, or tucked away single sites, this campground has something for eveybody! This last visit was for a camp wedding and birthday! They staff were wonderful and accommodating. I love this park, and I will always come back.
Did you know that Minnesota has glacial potholes? Neither did l. Interstate State Park has two-adjacent parks. There both on the border of Minnesota-Wisconsin. Both have the same names. The Interstate State Park has many trails. There's camping, canoeing, great scenery, wildlife, old lava flows and much more. Take more than a day to visit the Interstate State Park. Enjoy your time there.
