Very nice stay and nice people.

Im rating this stay a 2 because our linen had not been cleaned when we arrived. The floor had not been swept and there was mold in the air conditioner. On the plus side after notifying staff they came down and changed the linen. Manager on site was very nice.

The cabins were wonderful. They were nice and clean and we had plenty of space. The campground is super cute. We loved it.

It was very nice with the cherry on top being the fireworks show we could watch from our porch. Lake is a bit mossy but sounds like you know that from reviews. Need to advertise this as everyone i talked to never heard of it.

Stayed in cabin #5. The whole place is amazing and the KOA staff goes out of there way for you. We have decided to make this an annual trip.

Staff was very pleasant and accommodating. We arrived earlier than we expected to but our cabin was ready and they let us checkin early. Cabin and the whole campground was very nice. Clean and well maintained. Wonderful place to stay.

Beautiful KOA! Clean, cabins are beautiful, right on a little lake and across the street from a wonderful water park! Definitely a gem for those traveling through or who are looking for a relaxing getaway.

My family and I went out there to enjoy the weather and have a great time the cabins were great and weather was good! Only had an issue with arriving there and I had to go to two different cabins that were not clean but recovery for this was great! One of the employees said she could get me another cabin that is clean I told her I liked the one I had just left she said give me 20 minutes and it's

The cabin was spacious and very comfortable. Every member of our family had an absolute blast. We only regret that we didn't have more time to stay longer.

The camping cabin exceeded my expectations. It could have been a little cleaner & had Kleenex and a coffee packet(like a motel), otherwise it was perfect. The walking paths & grounds were in great shape & I enjoyed several walks. A very pleasant stay.

We rented one of the cabins, which was very clean and included all the amenities as described on the website. Campground was very clean and well maintained. Used the grill, picnic table and fire pit, had a memorable time! Beautiful lake!

the cabins are comfortable enough but the silverware and dishes need to be restocked and a few items should be added to the inventory.

Great experience.Great family weekend. Cabin was clean.

The cabin had a definite musty smell. No coffee maker available.

The cabins are very nice for a weekend get-a-way. I like the fact that linens are provided, unlike most KOA's I have stayed at. It's less I have to pack and try to fit into my small car. Great place to stay!

We loved the 'tiny house' cabin we stayed in that sleeps four. Can't wait to stay in the others that sleep six and eight! The lake, beach, playground and store were all wonderful. We look forward to staying here in the summer and enjoying the lake more and Lost Island Water Park.

Was Triple charged the deposit. None of the staff apologized or even gave me a reason why. They were rude and unprofessional. None of the staff wore uniforms. They were more interested in having a good time behind the counter than helping me. When one of their friends walk through the front door they yelled hey no losers allowed. The cabin itself had a giant stain on the bed.

We met there for a family weekend. The cabin was great. I like the fact that the linens were provided. Most KOA's do not provide linens in the cabins. It was one less thing I had to pack. The only thing wrong with the stay was that they were out of firewood. Very peaceful. Great view from the cabin deck.

The cabin was very comfortable and clean. Location was awesome to nearby Restrauant's. Only wish dogs under 25lbs, crate train would be allowed. Of course a re-fundable pet deposit would be okay.

We had an incredible time! Our family was able to use the paddle boats and play ground, play sand volleyball and enjoyed our time there. My friends were able to view the cabins and are reserving theirs for UNI graduation in May. We will definitely be returning next Family Weekend and plan to extend our stay an extra day/night just so that we can enjoy the facilities a little longer.

This is the nicest KOA I have ever stayed at! Karl and staff are extremely helpful and friendly!
Oct 04, 2016
cabin and grounds were clean and nice. overall had a good time. wish the wifi was better. the lake has a ton of moss making fishing difficult. I dont think they need to charge 5$ for a small bundle of wood for paying guests. seems like gouging to me. kids had fun, we might go back.

VERY poor 'beds'. It says it has bunk beds and 2 twins in loft, but all 4 of those are JUST mattresses, no box springs so not really 'beds' VERY uncomfortable!!! Get real beds for real people!
Oct 03, 2016
Loved it and will definitely be back again and again!

My daughter and I had an absolute blast during our stay, would recommend to any one!! Just a few complaints, the pillows in the cabin are terrible, wifi could use range extenders, and I suggest not selling day old donuts that are rock hard...
