Always enjoy staying at this KOA. Quiet and well run kampground and John and Kristi run a great operation.

Over night stay, clean park, lots of dead grass and weeds on our site, but not a huge issue for one night. Would not want to stay multiple nights due to dead looking sites. Awesome people working there, and the pizza was great. Pool was refreshing after a long drive.

The facilities were nicely kept. The bunk beds in the cabins were tight quarters with the top bunk being very close to the bottom bunk.

Simple and easy to pull in/hook up. The design though lead to some confusion about utilities. When we pulled up, our neighbor was using our sewage line. It was late at night so we couldn’t hook that up.

Nice, cool and refreshing pool. Friendly staff - moved us to a site with some shade - temps in the upper 90’s Clean rest rooms, but a bit of a sewage smell in there.

Owner upgraded our site, no charge, as we were staying longer than most other campers. Very well maintained. Convenient to the interstate but could not hear it. Close to the Battle of the Little Big Horn. Quick service for pizza orders. There is good tree cover for an area that has very few trees. This helps on the +90deg days.

We stayed for one night. We arrived at 2pm and since we left our vehicle/trailer hooked up, had a lot of time to kill. I spent most of the afternoon/ evening at the pool. The water was refreshing and lots of the area in shade due to the shade sails. The showers were clean. It's nice pizza is sold at the office for those who don't want to drive again. I heard it was good. The sunset was beautiful.

We had a full hookup pull thru site that was pretty tight. Otherwise all was good.

This is the 4th year we have stayed at Hardin KOA and it has been very good every year. Clean bathrooms, quiet camping and has everything you might need for your stay.

The owners of the Hardin KOA, Jon and Kristi, are wonderful hosts who take a hands on approach to providing their guests the best possible experience during your stay. We stayed two nights in one of the newly renovated sites (power, water, and sewer) and had a very nice time. The Park is a mile off the highway and very quiet. The facilities are nice and clean, and the store is well stocked.

The KOA and its people were just great. I stayed in a buddy site that was new to me. Our rigs were so close together that I couldn't open my awning windows on one side much less could hear every word coming from the other rig. I now know that I'll refuse such a site in the future.

Great host and excellent location! And the pizza is a must! service was great, reasonably priced and delicious!

The campground owners have done much work. We had stayed 6 weeks earlier, at the start of season. You could tell at our first time there they were working hard. As of this stay, the sites looked established with new electric and such. It's been a dry season so most of the greenery has taken a beating. Staff was very nice .

The woman that took care of our needs was very friendly, and easy to speak with. The camp was clean, and checking in was easy. The wind was not conducive to my cooking style ( BBQ and stir fry) however we made due. I would not recommend the pizza, I have a wood burning pizza oven that I carry with me, however , again it was the wind not the campground. I hope to return next year.

Easy access from I90. Friendly, helpful staff. The site was easy to get into and was fairly level. The utilities were good. There was a nice little pool and playground, which we did not use. Big fenced in dog park too. Everything you need!

Stayed here before. Place is much dirtier. It appears they don’t clean sites after people leave. Food remains, cooked aluminum foil, and dog feces litter the place. I know camper should take care of, but if they don’t, it does fall on KOA. The bathrooms had no tp. Only one men’s stahl worked. Hope it gets cleaned up, because there’s a Loves RV, same price/clean- removed from gas station.

The host was accommodating & moved us because our spot was extremely muddy on arrival. I think they upgraded us which was a plus, but the layout of the new spot allowed us to hear everything in the neighbors RV as the utilities are shared. Also, at no fault of the campground another camper ran their van all night long with the headlights on two nights in a row even after being asked not to.

Staff very friendly and helpful. Love the two dog parks. The restrooms were clean but need some work on the maintenance.

I cannot say enough with things about this KOA. The owners are absolutely fantastic and they truly care about your best stay! They go above and beyond! We rerouted our trip just to come back to stay for a night ♡

Great campground conveniently located off the highway. Sites are well spaced. Our site had full hook ups along with a covered picnic table. Hunt Brothers Pizza is located on site. The pizza and wings were delicious and it was great not to have to cook after a long travel day. They also have a nice gift shop with a wide selection of items and camping supplies. Hosts and staff were very friendly.
