Pretty nice wooded campground close to St. Louis! Each site has a picnic bench, a fire pit and grill. It was very quiet when we stayed there on a Friday night, but it go really busy on Saturday morning because the equestrian folks use the campground as a staging area. There are two trail heads near the campground(very nice hiking!)
Sage Creek is a free and primitive campground in the Badlands National Park. It is absolutely beautiful and surrounded by grassland. The only amenities are vault toilets-there is no water at the site, but you can fill up at the outside faucet at the visitor center before heading down the road to the campsite. There are 12 miles of gravel roads (some great pull offs along this road for pictures) to get to the site, so low clearance vehicles may want to watch out when it rains. The early morning is awesome at this campsite, its quiet, the sun is rising over the hills and sometimes wildlife can be seen munching away.
The bison frequently roam through this site and I urge all campers to stay a safe distance from the bison as they are wild and unpredictable.
The only complaint I really have about this site, is more of a concern. In recent years there has been a problem with over crowding at the site, for example, more people staying than allowed, people driving and camping outside the designated campgrounds, being loud, crowding other campers, etc. While we were there, we saw a truck barrel over a prairie dog town, parents allowing their children to throw things at the prairie dogs or stick things into the animal's dens and an argument over a campsite. I just hope that those who choose to camp here keep the park rules and the leave no trace principles in mind. This is a beautiful place and a joy to visit the quiet grasslands.
