One of the best camp grounds we have ever visited. Stayed in a motor home towing.

Very pleasant, accommodating and helpful office staff. Very nice park. Would love to bring the grandkids back in the summer.

Lots of nice things, great store, fuel stop, clean laundry, despite a dryer not working. The campsite were pretty marginal, a number of full timers all packed into the open portion, just an O.K. place to overnight.

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!

Great stay!!! Beautiful campground that was very clean, the employees were very polit and helful. We are already making plans to return next camping season. With this being the first KOA we have stayed in, we plan to stay in many more. Thank you for the great experience.

Great family campground! We enjoyed a beautiful weekend in November with kids and grandkids. Want to thank staff for help as we had a problem with our pop out and 2 hours late leaving. Love this KOA camp!

Nice, large sites. Bathrooms, including showers were cold and not cleaned entire time of our stay.

I loved the campground and all the ammenitites however the service was terrible we asked to have a light bulb put into the pole where we were staying and the staff said they were too busy but they would try, it never got done.

Friendly staff, nice park generally, but the rest rooms really needed cleaning.

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.

Super stay. From reservations made 8 months earlier to check-in and overall facilities.

That was our second visit this year.

The stay was great. The only issue was the traffic in the campground. Traffic in the campground were going to fast & there was a lot of it.

It exceeded our expectations. Pet friendly atmosphere was a bonus.

Great park and campground. End of season so a little lacking in housekeeping in bath houses but overall a great campsite.

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.

Our first time at this KOA. The sites were spacious and the setting was wonderful. Not many trees yet in this newer park, but can't wait to go back in warm weather and enjoy all the amenities. Great place to get together with family.

Very nice sites and friendly staff.

We loved our stay! Being right next to the fishing pond was a beautiful experience. Our only concern was we had a disabled person with us and the showers and store were quite a ways away from where we were in the park, but it was our decision to request a spot right by the pond...so - this is really a nice KOA!

One of the best KOA's we have stayed at, friendly staff!

Very clean, nice quiet campground. Staff in store (young lady) was very pleasant.

We always enjoy staying at the Waterloo KOA. Relaxing and love the space between spots. Will definitely be back next year. Sadly we're done for the year.

It was excellent

Very nice location, staff is awesome, and all the amenities we like!
Oct 07, 2016
Campground was well kept, but far too close to the freeways. We knew this before we showed up, but is the main reason we are downgrading this campground. Bathrooms were very clean, but we disliked the push button control for the showers.

We've camped at many KOA's across the US. This is one of the nicest, cleanest ones we've stayed at. It is a resort with many activities for kids to do.Playset is awesome. Bathrooms are spotless as well as office. Everyone very nice. Visited for Halloween activities with grandkids. They loved trick or treating and decorating camper. They loved the beach area. Hayride was run too. Cabins beautiful.

Great stay. Wish a better base is put down on pads so jackstands don't sink into the pads. Happens all through the summer.
Oct 06, 2016
This is the nicest KOA I have ever stayed at! Karl and staff are extremely helpful and friendly!
Oct 06, 2016
Poor reception, not escorted to site. Site not level. I am an exclusive KOA camper and will avoid this one in the future.
Oct 05, 2016
Fantastic campground
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.
