The Kampground itself was fantastic. Lots to do and quiet. The pond was a bit yucky to swim in. However, we had a blast playing sand volleyball. The cabin we rented was very nice but not clean at all. I did let the lady know at checkout and she was very apologetic. I will stay again though. Just will bring my own cleaning supplies.

We thoroughly enjoyed our stay. We rented a cabin and found it to be a great option. A nice and relaxing getaway.

We had a great time visiting Lost Island Waterpark and then staying in the deluxe cabin. The kids loved the beach. The only downside to the beach is all the goose poop, especially on the island. We are definitely up for making this an annual stay.

We had so much fun. Right on the little beach. Cabins were really nice! It is a new campground so the trees are small, once they grow it will be even nicer. We plan on returning next year.

It was a very nice stay. I was hoping for a little bit bigger cabin for the five of us, but for the amount of time we were in there, it was nice.

everything was wonderful except the pullout bed, it was unfit for most anyone. Everything else was perfect!

Great stay and nice campground. Kids loved swimming in the lake!

My family and I enjoyed staying in the cabin there. The only thing I would recommend is of guests are expected to clean before leaving, cleaning supplies should be provided such as disinfectant spray and paper towels at the minimum. There was a broom to sweep.

Had a great time loved the cabins. Better pullout beds and retractable awnings on cabins would be awesome

The campground was awesome. Very clean and friendly. The only reason we did not rate it 5 stars is the distance you have to walk to get to a shower. Had Sr Citizens with us and unlike every other KOA that we stayed at, this one's shower was a long walk that at night was not lighted at all????
May 17, 2015
Everything was awesome. The people who took care of my transactions were great. This is a great place!
May 15, 2015
We had a wonderful time my grand kids went fishing for the first time.The cabin that I stayed in did not have a coffee maker in it, Carl went and got a new one, not that is service,thanks can't wait for our next camping adventure in July.☺

May 12, 2015
It was wonderful. We have been before and we will retune again. It is clean and quite. We will be back because both of our boys are attending UNI. Better then a hotel in my opinion. Thank you

Loved the campground and the staff was super friendly and accommodating.

The staff is so friendly! I wish the cabins had more dishes etc. but I other than that, I love the cabins and having everything right there at the store too! With all the hustle and bustle in my life, it is so peaceful to stay right by the water.

Very Clean!!!

Cabins are super cute. One cabin had bed bugs and we were with many family members forcing one family to stay at nearby hotel. HUGE bummer! Wish they would have checked the cabin beforehand.

Great place to stay...so many activities to do there and the cabins are very nice. Wish we could reserve for just one night instead of a two night stay rule.

We had a great time, thank you for having us. My grandchildren did not want to leave, and the cabin was just perfect for all eight of us.

Really enjoyed the cabin that we stayed in for the second consecutive year. Missed having the billiards table and table tennis game in the game room.
