Things To Do


Whatever outdoor activities you enjoy, you'll find that a variety of recreational opportunities await you at Interstate State Park. It's Wisconsin's oldest state park, established in 1900. The park is in Wisconsin's Forest Transition landscape, across the Saint Croix River from Minnesota's Interstate State Park. A deep gorge called the "Dalles of the St. Croix" is a scenic feature of Interstate State Park.

There are several opportunities throughout the year to take part in nature interpretation and environmental education:

Summer naturalist programs are offered from the Friday before Memorial Day, through Labor Day. Explore the trails, ponder the potholes, or hear the colorful history of the St. Croix River valley during a guided hike or activity. In the fall, special activities may be scheduled to take advantage of the area's beautiful colors.

The Wisconsin Explorer program offers another opportunity for adults and children (ages 3 and up) to learn about nature together. Activities are clearly described in the free Wisconsin Explorer booklets, available at the park office and the Ice Age Center. A child completing at least half of the activities can receive a free patch.

At the Ice Age Interpretive Center, open weekdays from 8:30 a.m. to 4:30 p.m. and weekends from 11 a.m. to 5 p.m., visitors can view exhibits to learn about the frozen history of Wisconsin and the gifts of the glacier. In the auditorium a 20-minute film, "Night of the Sun,"the story of glaciation in Wisconsin, is shown daily at 11 a.m. and 1 and 3 p.m.

  • Boating

    A boat launch provides access to the St. Croix River and the interesting rock formations on the Dalles of the St. Croix gorge.

  • Camping

    Wisconsin's Interstate Park has two campgrounds with a total of 85 family campsites, and a primitive group camp that accommodates 60 people. Advance reservations are recommended and also can be made by calling toll-free (888) WI PARKS ((888) 947-2757, TTY (800) 274-7275).

  • Fishing

    The St. Croix River offers anglers the opportunity to test their luck and skill.

  • Hiking

    The best way to discover all that Interstate has to offer is by hiking some of the park's nine miles of trails. Frost action and weathering over the years have formed interesting rock features such as the Old Man of the Dalles and the Devil's Chair. Also, water from a melting glacier swirled sand and rocks around to carve potholes in the bedrock. Be careful when exploring the rocky areas and rimrocks!

  • Picnicking

    Picnic in any of several different areas of the park. Picnic tables and grills are available, as well as open shelters that can be reserved for group picnics.

  • RVing

    RV sites are available.

  • Water Sports

    There are an excellent swimming beach and Beach House at scenic Lake O' the Dalles.

  • Winter Sports

    A 2-mile snowshoe trail starting at the Ice Age Center leads to an area of the park not easily accessible other times of the year.


Open year-round. The park is open from 6 a.m. to 11 p.m. every day.
