The South Campground at Interstate State Park offers 44 rustic campsites (no electric hookups) with vault toilets and drinking water, conveniently located near the park entrance.

Sites 65 and 67 provide direct river access via a ~350-foot path to a small beach, making it an ideal launch point for kayaking on the St. Croix River.

The campground is open year-round and operates on a reservation system; winter camping (Nov 15-Apr 30) is tent-only with hike-in access.
