I should have checked Recreation.gov to confirm this campground is open before heading there, it would have saved me some time. It closed as of September 11th 2020, and is reopening in May 2021. Looks like May- Sept. is what's planned for next year as well. Boo! Still, glad I did actually go because now I know where I might head next time I'm in the area. Noticed some other campsites in the Black Hills are closed as well, so I might have timed my camping trip to the area poorly. Live and learn. Anyway, about the campground… 

Easy to get to, good LTE reception on Verizon throughout, BIG area with what looks like four different loops, some closer to the water than others. A tent-only area, which I appreciate- those tend to be quieter than the RV spots, and the tent area was close to the reservoir. Standard campsite amenities- tables, fire pits, bathrooms. Swimming seems like an option. Plenty of trees for us hammock dwellers. Could easily see myself spending a few days here when it is open, assuming it isn't too much of a zoo, which large sites like these can devolve into.

NOTE: this is a duplicate listing of another Dyrt listing for the same campground. That listing is under the name "Pactola Reservoir Campground" which is the accurate name according to the Forest Service. That listing has more reviews and info, but has incorrect GPS coordinates. I've submitted a fix, so hopefully they'll fix the GPS for the other listing and merge them, but until then, just a heads up. Here's the other listing: https://thedyrt.com/camping/south-dakota/south-dakota-pactola-reservoir-campground
