Located along the picturesque St. Croix National Scenic Riverway, the park provides scenic views of the river and the steep-sided gorge known as the Dalles of the St. Croix. More than 9 miles of hiking trails, including the western end of the Ice Age Trail are found within the park. The Ice Age Interpretive Center features a film, photographs, murals and information about the great glaciers. Over 80 family campsites, 2 group sites, several picnic shelters and an amphitheater are reservable.
Is Interstate State Park fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
CampHawk watches Interstate State Park in St. Croix Falls, WI for you. We recheck it every 15 seconds, around the clock, and the moment a site opens we send a text, an email and a push notification, with a link straight to the booking page.
Searching is free and needs no account — the calendar above is live right now. Watching Interstate State Park for cancellations is the paid part.
