My review of this park is perhaps colored by the site we ended up getting, but I see a number of like situations in this campground, and it seems non-trivial. Basically, in order to maximize the number of sites, in many cases they've placed adjacent sites so close to each other, or in such a haphazard way, that rigs end up literally sitting nose to tail, or door to door. Fine if you're with friends, but not so fine if your next door neighbor has yappy dogs. Or likes to play his music, or whatever. Big, big park, lots of spaces. Not all of them OK. We stayed in site 144, but it is only one example. Staff was OK, but certainly nothing spectacular. Won't be my first or second choice next time.
Nice park, nice folks. Spaces are a bit tight, but nothing out of the ordinary. Gravel pads and driveways, which means some dust when the wind kicks up, but oh, well. Staff was very helpful and friendly, and went out of their way to answer questions. The park offers (I assume only in the summer) a grill menu in their pavilion, with emphasis on steak, ribs, etc. Certainly not haute cuisine, but just fine for the money. Also offer pre-ordered muffins, but I felt they were way, way too small for the $1 they cost. We'd definitely stay here again.
Unless you own an ATV, UTV, or dirt bike, I strongly recommend you find another park. This park is a large, wide open gravel area that caters to folks riding the aforementioned toys. As such, it's loud, and very, very dusty. Staff isn't the friendliest, and at times seem far more interested in the attached gas station and convenience store. But the biggest turn-off is the noise and the dust.
Major "it" factor for this campground. Beautiful meadows, beautiful views everywhere. Enormous sites, with either shade or sun, in 5 different camping areas on the 167 acre site. Very kid and family friendly, without a lot of noise. Small camping store, pancake breakfast every morning (all you can eat, $2.50), just outside Hill City, SD. Bit on the expensive side, but well worth the money.
Park was very crowded, through no fault of the campground. Every, and I mean every, other campground in the area was flooded out. Campground was very quiet at night, even though there were a lot of folks. Park is small enough that the owners know what's going on. Sites were adequate although not spacious. Folks running the place were very helpful, to include guiding us to, and then getting us in our backin spot. Small, though expensive grocery. Good for the forgotten milk or laundry detergent. Laundry available, $1.25 for wash, $1 for 45 minutes of dryer.
