Sooooo. This may be redundant to the previous reviews. However as of Oct 27th of 2025 , the owners are the key to this park. Yes. Clean, well taken care of, but the owners make every effort to make you feel welcomed, and do almost anything you make think of to be a great host. We think if you're anyway near this park it should be your first option. Michelle n Gregg

Great KOA! Owners are so accomodating, helpful and friendly. For me the most awesome thing was there DOG WASH ROOM! Wow, did my dogs need baths and it is the best set up! These owners have only been here 2 years and they have great vision and are making improvements. That said, the laundry room was great, the pool was great, the store and pizza also great! Thanks guys, our stay was very pleasurable!

Beautiful location. Nice, peaceful and quiet with a beautiful sunset view. The campground is very clean, including the pool and playground. We LOVED the little store/gift shop and pizza shop. And the pizza is SO good! Husband and wife owners are very kind and helpful. :) Thank you for a peaceful rest and the yummy dinner that we didnt have to cook! Haha.

This is a great place to stay. The owners were super friendly and accommodating. The dog park is exceptional. It was much bigger than other KOA dog park and it was clean. I would recommend replacing the sheer curtains in the women’s bathroom with something more private as you could look in and see everything when walking by. The men’s restroom did not smell good either.

⭐️⭐️⭐️⭐️⭐️ Great Stop with Clean Facilities and Friendly Hosts! We were so glad we made the decision to stay at the Hardin KOA on our journey home — it’s conveniently located not far off our main route and offered the perfect place to rest and refresh. The hosts and staff were incredibly friendly and welcoming, and the campground itself is peaceful, with beautiful views of the surrounding prairie. One of the highlights was the immaculately clean laundry room — seriously one of the best we’ve seen! At just $2.25 for a wash and $1.50 to dry, it was both affordable and spotless, making it easy to catch up on laundry during our travels. Whether you’re just passing through or staying for a bit, the Hardin KOA is a great place to stop, stretch out, and enjoy a quiet break from the road. We highly recommend it!
