We’ve stayed in several campgrounds in the park and Stockade South is one of our favorites. It’s small and quiet and positioned nicely to do either the Needles or the Wildlife Loop and is also close to Custer if you need supplies. Folks are super friendly here. Flush toilets and hot showers. We camped in our van with electric h/u but there are also tent sites and cabins. Some sites have nice big stone fire pits and ours did not, so don’t choose site 13 if that’s important to you. 25$
