There are more than nine miles of hiking trails in the park that offer the walker many opportunities for viewing the spectacular scenery and natural attributes of the park. Guided hikes are offered during the summer months. Pets must be on a leash 8 feet or shorter at all times. Hiking trails vary in difficulty. Not all trails are surfaced; use caution on steep bluffs and near cliffs. Trail surfaces can become slippery when wet, leaf-covered or where there is loose gravel.
Interstate Park is in St. Croix Falls, on Wisconsin Highway 35 just 1/2 mile south of U.S. Highway 8. The park is open from 6 a.m. to 11 p.m. every day. Geographic coordinates are 45° 23' 34.93" N, 92° 38' 26.57" W.
