No, you cannot camp anywhere in the Badlands. In Badlands National Park, camping is only allowed in designated campgrounds. There are two campgrounds within the park: Cedar Pass Campground and Sage Creek Campground. Cedar Pass Campground has amenities like running water and flush toilets, while Sage Creek Campground is more primitive and offers pit toilets. Outside of the national park, there are several private campgrounds and ranches in the surrounding area where you can camp. You can find various accommodations, including tent sites, RV sites, and cabins, at Hipcamp's Badlands camping page. Please remember to follow Leave No Trace principles and respect the fragile ecosystem of the Badlands when camping in the area.
