Big Island — Saint Croix National Scenic Riverway

River access drives most visits to Big Island, a National Park Service campground along the Saint Croix National Scenic Riverway. The site sits on an island formation where paddlers can launch directly into the water for downstream runs or fishing excursions. Basic facilities include vault toilets and fire rings, though campers should plan for primitive conditions without electrical hookups or potable water on-site. The campground operates seasonally and requires advance reservations through the National Park Service system.
