Had a great time. Cabins were nice and warm.

Stay was great. They were very awesome to work with. We recommend to anyone who has a student at UNI and needs a place to camp.

Unfortunately I arrived during the off-season. I can see this place being a lot of fun during the height of summer. Very handy having a petrol station as part of the site.

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.

This was our second stay at the Waterloo KOA. We love the location to visit family, and like that the grounds are dog friendly with a nice lake to walk around. The location is very clean, and the staff is helpful and friendly! We plan to continue to visit a couple times a year!

We recently stayed at this KOA for an extended period of time because my daughter who lives in Iowa was having a baby. We have nothing but good things to say about this KOA. The facilities are nice and set up for ease of use. There is a gas/diesel station on site. The store stays open until 10:00 p.m., and the staff was friendly and helpful especially Karl. This is an exceptional KOA campground!

Very customer friendly staff. Great location for warmer camping. Beach, swimming, beach volleyball, tropical atmosphere, and more would be great for family reunion and group meetings.

The ground is eroded and rough in spots. I turned my ankle while setting up and walking to the dog park. I am OK but it may be an issue to someone else.

The area for picnic tables at site was not level- difficult to sit out and found staff were not as helpful as expected at a KOA

Staff were very friendly and campground was nice and neat. Great place to stay, lots of activities around.

Wonderful - the best KOA so far for us. The manager, Karl, was so helpful and went above and beyond to make our stay enjoyable.

We enjoyed the time of year that we stayed at the park. I would not want to stay when it is full of people. Spaces are way too close. However, the space we had was very nice with the concrete patio, fire pit, and furniture. The layout is very confusing trying to find the best way to the camping spot. Also needs more signage to get to the park itself. Overall we would stay again.

Wonderful place to stay. Campsite was large and roomy. Will be better once trees grow in. Staff was friendly and very helpful. Ice machine was broke which was a hassle. We had to drive to buy ice. Not many people camping but cost was still on high side. I would think there would be an off season rate or discount when so few people are there. We will be back and will try other KOA sites.

Very nice park, will return

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.

nice and clean, everybody was so friendly, our son & family live in Waterloo, and said they would like to camp here.
