While there are no free campsites within Badlands National Park, you can find free dispersed camping on nearby Buffalo Gap National Grassland. The grassland surrounds the park and offers primitive, undeveloped camping spots. Keep in mind that these sites have no facilities, so you'll need to come prepared and follow Leave No Trace principles. To explore camping options within the Badlands, you can visit Hipcamp's Badlands page for more information on available campgrounds and accommodations.
