Hardin KOA
You can tell they are putting a lot of effort into this KOA. Spacing is tight and off season has only water available at middle rows. Road and airport noise. Was a great stop on our way. Friendly owner.

We stayed for two nights and made full use of the park. It was quiet during the day.
Nice place to camp. Sites are far apart, so some privacy too.
This spot is great for a night. Right by the river, pit toilets, and a garbage can. A local said teens come down at night but we were here midweek and the children are back at school. Quiet spot near the road but little traffic noise.
Only 7 days max as insufficient access site but 45 minutes from Billings and a beautiful quiet location if you can deal with the train going by half a mile away and blowing its horn every 2 hours
Description doesn’t say they only do weekly and monthly rates
Pull thru and back in sites available. Mostly full hookup sites with some electric only. Clean bathroom and shower. Laundry on premises. Close to Love's travel center. The surrounding area is not very attractive but the campground is well maintained.
Was able to pull in late at night and stayed in a private pull through site at the rear of the campground. While I was there, there was an individual mowing.
What that I suggest is when you're camping with no power maybe go down a little bit on price but otherwise it was nice
