The owners were some of the nicest folks I’ve ever met. The campground is well kept, clean, and quite. I enjoyed buffalo wings but they also had great smelling pizza. The laundry room was great and included vending machines with very thoughtful items campers might need.

The campground was fine for passing through. But the electricity on the site they put us in was not grounded, fortunately they moved us to another site.

It will be a great place to stay once they finish the upgrades. Ib loved my stay here it was very noisy due to renovation. I would recommend this KOA to my friends and family but I would say check in to see if the renovation is done so you can enjoy a peaceful time durning your stay.

Very attentive to guests’ needs. We stayed two nights, 6/1 and 6/2. They were working hard to get everything opened back up & ready for guests. Bathrooms are a little older and could use a little more space for undressing/drying/dressing but plenty of hot water and good water pressure. Nice, quiet place. Perfect for overnight stop. Nice gift shop. Hunts Bros pizza! Would def stay again.

We stayed here for 1 night between deadwood and Yellowstone in late May. Campsite is perfect size and we would definitely stay there again. The owners were great hosts, friendly and available on site. Nice clean shower, laundry and pet wash station! The store had really cute selection of items. If you are bird watchers this is a great spring spot.

Well kept campground. Looks like they are expanding. Only downside the town of Hardin doesn’t have much to offer

We really liked that the KOA site was a mile from Hwy 90, quiet & open spaces around the location. We will always remember the staff with a sigh; we needed a vet while in Hardin. Our Lily had been ill, & it was time to help her to the other side of the rainbow. John gave us the name of the vet he takes Jack to. Between John's concern & kind office staff; a sad occasion is now a fond memory.

We stayed in Hardin at the KOA for 4 nights. The staff was helpful and friendly. They have a pizza parlor right on the property, which was a nice convenience. The park itself is surrounded by open farm country and it's a very peaceful spot. The bathrooms and showers were spotless.

Grounds were a bit unkept. Owners were very friendly. A lot of construction going on at the park. Bathroom looks very old but was clean. Showers need shower heads.

Fantastic place

This was a nice value. The hosts were friendly and enthusiastic. WiFi was great. If you’re too tired to cook they make fresh pizza in their little restaurant. Could see where they are expanding to provide some larger pull thru spots.

The new owners are working hard to bring the KOA back up to park standards good job so far. Our one night stay was relaxing and peaceful. We will stay again on our next trip through.

This was a very nice campground . We toured the Battlefields just 20 minutes away. It was the perfect location, very quiet and all the amenities we needed. They have great bathrooms, laundry room. Firepits, lots room between campsites. Easy access from the interstate. Also a cool store with souvenirs , camping supplies etc. Although we didn't try it they had wings and pizza .

Park is really shaping up as owner is putting in new sites, and prepping for the busy season. Excellent staff, and my site was just fine and very quiet. Close to a truck stop, restaurants and more. Would stay here again for sure.

We stayed for just one night but the staff was very friendly and accommodating. We had a package sent there and they called as soon as it arrived. Roads and sites are gravel. Al very level. 2 very nice, large dog parks. They have a pool, playground, etc but we did not use anything. We would stay here again.

My family stayed for approx 4 nights for the battle of little bighorn 150th anniversary. It's a pretty nice, clean, and well kept KOA. I would highly recommend staying here whether using the cabin, tent, or rv. The grass is well maintained and the campground is decently lit where needed at night. They have a lot to offer in the offices' giftshop. My only complaint would be the gray cat I saw pee and poop near the tetherball pole in the sand where the kids play. My kids still played on the equipment each day but I had them keep their shoes on from then on. They really enjoyed the slide, teeter totter, and cornhole. We did not get a chance to swim but saw other kids and adults enjoying it! The showers and bathrooms were very clean and are cleaned from 11am-1pm daily. The women's has 3 toilet stalls and 3 shower stalls and with the site super packed during our stay, the stalls stayed available.
