Campground Reviews

Nice quiet campground- owner very helpful. Nice store & pool.

The campground was clean and comfortable. The sites were big and level. Our only problem was that the campground hauls in their water and our last morning the campground ran out of water. It was only for a couple of hours but still a little inconvenient.

Owners were very nice and accommodating, and they had some fun outdoor games. Bathrooms were clean, and showers were great. Cabin was not the cleanest. It was pretty dusty inside compared to other KOA cabins we've stayed in.

Had a nice larger site, two dog parks not just one. The playground look like a lot of fun for kids to use. Laundry facility was good to use, and fairly priced. The KOA host for very friendly and nice to talk to. They keep a nice clean the property. Highly recommend if you're passing through.

Close to interstate but quiet. Easy in and out. Owners very friendly and diligent. Stayed 3 nights to see surrounding attractions close by. Little Big Horn Battle Field and county museum very close. County museum was quite remarkable! Good pizza and wings on site!

Friendly staff. My only concern was we were under trees and no fault of anyone but the birds defacated all over a 450, 000 motorhome.

This was one of the very best KOA's we have been to. we have been traveling across the country from Pittsburgh and have been to many many KOA's. Thank goodness we did not listen to someone in a close town who said not to stay in Hardin. We chose to see for ourselves and it was worth it. This is the cleanest, family oriented, kind people, safest stay we have had. Owners are wonderful. Thanks!!

People were very friendly and helpful, Nice little Ma and Pa campground. I did feel they need to do a little maintenance in the bathroom. Some latches needed repairs and garbage can in bathroom needed cleaning. Covers over the sewers instead of rocks might look nicer. We did like the pull thru ability better than the back-ins. Will definitely stay again.

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.

Got us in last minute- level sites - cute little store and very friendly

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
Jun 02, 2026
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.

This was an overnight stay. The campground owner was very friendly and very accommodating. They are expanding the offering sites. Would highly recommend.

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.

Stayed two nights here to visit Little Bighorn Battlefield.The hosts were great and the campground was nice safe and secure. Stayed in cabin #3.I always have a nice stay at KOA.

Staff was phenomenal and the dog park area is very large.

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.

Found dirty socks under a bed. Other than that it was great

Fantastic place
May 23, 2026
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.

Very nice and comfortable RV park It was conveniently located off the highway yet it was far enough to be quiet. Would definitely stop in again

John was a great host.

Always enjoy staying in Hardin with Kristy and John who are great owners, friendly, professional, and provide great customer service. For the past 3 years they continue to make upgrades for customers.

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.

Great Campground, and here's why. I have stayed in 11 different campgrounds in the last 10 days and this one is one of the top two. 1. Hosts are friendly. 2. Easy access 3. Campground is clean and well maintained. 4. Pool and pool area is nice. 5. Playground for kids. 6. Restrooms are clean and I mean clean. 7.Great WiFi. Would definitely stay here again, and recommend to travelers. One minor problem with campground, my recommendation to the owner is you have a bird problem that should be looked after daily if you know what I mean.

The couple who own and run this KOA are some of the nicest folks I've met. The facility was wonderful, laundry, showers, pool, quiet, clean, exactly what you want when camping. I'd go out of my way to stay here.
