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.

Fun place to explore . We have been here several times as we live close by. You can meet people from all over the country and world for that matter. A chance to realize we all actually like and respect each other. Put that on the evening news!
I really had a good time at the Minnesota side of Interstate State Park today. There was a logical 3.8 mile hike through the park's three most important trails that was a high quality workout on hilly ground near the river as well as providing an assortment of great views and photo opportunities. Of course, the highlight was the climbing--there was plenty of boulder space available with lots of novice climber friendly problems. I didn't try the roped, but there were plenty of people there for that who seemed thrilled. Really enjoyed this park and would definitely recommend!
