The park has two separate areas, that offer two unique experiences. The riverway campground/area is the more popular part along the St. Croix river. We booked a last-minute site at the Savanna Campground, which is more inland, although hikable to the river. This campground is pretty crowded and we dealt with some rowdy neighbors. The Park Rangers monitored the park frequently, so this is definitely not a peaceful, off-the-grid campground. But it's less than an hour from Minneapolis, and offers lots of great (and well-groomed) hiking trails.
