One of the best KOA's we've been to and we've been to a lot. We also stay at KOA during our vacations and this one we will stay at whenever we visit our son in Waterloo.

The men's shower room was a bit dirty

This KOA needs to work on improving the grounds. The grass is growing in clumps, and if you don't pay attention you could trip. If the grounds were better maintained it would be a great campground. We love the fenced in dog area, and the lake is beautiful. Restrooms are clean.

It was a nice weekend. Showers could have warm water, Grass could be shorter for Frisbee golf, Dump stations run up hill so it is almost impossible to dump completely. Staff was great store seemed to be spot on with items you may have forgot. plenty to do, had a lot of fun.

This park will be amazing in a few years when the trees mature. The only thing that I did not like was the painful jet of water from the shower. Would not be able to take a small child into this shower. This needs to be changed. Also would like to be able to control the water temp.

One of the best KOAs we've stayed at. It's new, but the grounds & staff are great

Thanks for use of cabin for showers. You really need some upkeep, the camp bathrooms should have been open and the grounds spiffy year round.

Banner at dog park is broken. Can hit someone in the face if they are unaware. Laundry room was being used by staff and totally full of cabin linens and not neat or clean at all. Otherwise staff is friendly and helpful. Walking around lake was pleasant except for geese but not much they can do about that. Road noises were not too bad considering location. We enjoyed our stay and will be back.


Thank you for the suggestions, we'll certainly fix both issues. We're glad you enjoyed your stay and look forward to seeing you again!

The Manager and staff at the Waterloo KOA are all friendly and courtious. This time we stayed in the cabins. They were clean and bright and at this time of year(winter) warm and comfy.

Great amenities. Fuel and air for RVs on site. Hilly terrain but level sites. As of fall 2013, the trees need a few years to mature to get a perfect score. Staff was very helpful and friendly.

Bathrooms NEED to be cleaned on a daily basis, but they clearly are NOT!!! Other than dirty bathrooms with dead bugs and leaves all over floors, and geese droppings EVERYWHERE this would be a nice campground. I hope staff starts to take better care of property or this place will be ran into the ground. Would be nice campground if they get staff that cares! Other than that it has lots of activities

This KOA has a wonderful theme and is near a casino, shopping area and many restaurants. Good place to stay.

The tent area could use a lot of improvement. The patchs of weeds made it very lumpy

Brand new and when they get the bugs worked out and the trees mature it will be exceptional. Speaking of bugs, there were only a handful of guests the night we stayed yet the bathroom sinks were full of bugs from the lights the night before. This was at 4PM and still there at 10am the nest day when we left. Even though it was off season and low usage, this needs to be addressed daily.

Great potential. Too bad the sites aren't paved. The sign at the office is too small. Streets are somewhat confusing.

What a nice campground.

1. The people at the desk don't know what sites are level and I don't think that any of the sites are level? 2. As confusing as the roads are, one would think a guide to the site might be needed! 3. The dry dog poop around the site tells me that no one checks the sites. 4. My perdiction is that this park will not last long. I know that I won't be coming back there.

great new park. lots of stuff for big and little kids on site and nearby.

Beautiful campground. Loved the beach and walking path. The multi-colored Kamper Kabins are very attractive. We will definitely visit again. Did not care for automatic showers. Very clean and modern facility but shower water comes out cold and shuts off automatically so has to be restarted.

We camped for two nights (Fri. and Sat.). Nice weather and nice evenings around the campfire.

It is not a campground, it's a waterpark. Just too big and empty of any kind of landscaping. Also, the workers acted like we were a bother to be there and did not tell aabout any services or conveniences at the campground.

We only live 60 miles away from this campground and did not know anything about it until our son-in-law found it and arranged for us to all meet there for the weekend. Very friendly and helpful staff and very nice cabins. We will absolutly be making it back in the future.
Sep 15, 2013
1. site numbers could be more visable. 2. bird poop everywhere and trash everywhere. 3. interstate traffic noise
Sep 15, 2013

The Kabin was wonderful. The staff extremely friendly and helpful. We definitely will stay here again!!

We loved this park! The trail around the lake was a nice run at just under a mile and we even got to play ping pong in the rec center. Because it's so new, we were able to reserve a full-hookup spot just before the holiday weekend. The park will look even better once the trees all grow another 10-15 feet taller and fill out.
