Interstate State Park, at Taylors Falls on the St. Croix River, is the geological highlight of the valley. The St. Croix River Dalles are a gorge of steep cliffs cut through ancient lava flows, and the park’s trails lead to glacial potholes, circular pits ground into the rock by meltwater from the last ice age. The park information notes that at least ten different lava flows are exposed, along with two glacial deposits and traces of old stream valleys and faults, which makes it a living geology classroom. There are about four miles of trails, canoe rentals with shuttle service for flat-water paddling, a campground and a large picnic area. In spring there are wildflowers, and in autumn the river valley is among the most colourful in the Midwest.
Planning
The park is a Minnesota state park, so a vehicle permit is required, either a daily permit or an annual one; check current fees on the park page. The address is Milltown Road in Taylors Falls, around an hour north of Stillwater by road. Camping is available, and sites should be reserved ahead in summer. Weekends in summer and autumn are busiest, and a weekday visit gives you the trails to yourself.
What to do
Walk the cliff-top trails for views of the Dalles and the potholes, and look for the volcanic rock layers explained by interpretive signs. Canoeing on the flat stretch of the river is a relaxed way to see the cliffs from below, and boat tours from Taylors Falls are another option. Watch kayakers run the rapids from the shore. Children enjoy the potholes, but keep close watch near edges and cliffs, wear grippy shoes and stay on marked paths. Dogs are generally allowed on a leash, but check the rules for particular trails.
Making the most of it
Combine the park with Franconia Sculpture Park, which is just down the road, and the Gammelgården Museum in Scandia for a full day of valley sights. The park also pairs with the Interstate Park rock climbing experience for adventurous visitors. Bring water, snacks and layers, and photograph the Dalles in the morning when the light is good. The park is a good wet-weather alternative only if the paths are dry, because the rock can be slippery after rain.
