Great free campground in the Badlands Wilderness area. Follow Sage Creek Rd and watch for signs for the campground. Made it no problem in a 26’ motorhome, but it is a 12 mile dirt road with a lot of washboard so things get rattled and covered in fine powdery dirt. Totally worth it though because on the way out you get amazing views from the top along the ridge of Badlands plus bison, pronghorn antelope, bighorn sheep, coyotes, and hundreds of prairie dogs along the road on the way.
The campground is a loop that has parallel parking around it and sites are designated by numbered posts. There is a horse camp area to one side and toward the right as you pull in and many people just made up spots not in the loop but behind the bathroom and along near the horse camp, so if you made the long drive out you should have at least somewhere to squeeze in for the night.
There are picnic tables, some which are covered and two pit toilet bathrooms. Also there is garbage and recycling. There is no water here so be sure to bring enough as temps can get quite hot. Some reviews mention the wind being an issue and though it was windy at first it died down and was calm all night.
It was nice when we were there in late Sept. There were plenty of empty spots in late afternoon but filled up through the evening. Bison frequently come through the campground and use the posts to scratch themselves. Don’t be an idiot though (we saw some of that) these are huge wild animals and do not want selfies with you!
There were also a lot of coyotes that came through at night so be aware if you have a pet.
Weak and spotty cell reception with ATT and Verizon and no TMobile.
