There was little to complain about. 1) The restrooms were not cleaned daily from 12-1. (2) They ran out of firewood and the ice machine was on the fritz. It did not affect us much, but could have been a big problem at the height of vacation season. These were minor things and we would definitely stay there again and recommend it to others.

We rented the 6 person cabin and had a pull thru site. There was 10 of us(6 adults, 4 children). We had an awesome time!! The campground was extremely clean, staff very friendly. The weekend activities were great fun. We will be back!! There was not one negative. This camp will only get better with the maturing of the landscape. Thank you.

very clean, had activities for the weekend, grand kids loved it. Lost Island water park not open as yet, but very close to it, so we did go carts

Family liked it very much, plan on returning later this summer when water park is open

The showers were clean and well kept. The dog park was a plus. It was close to everything we needed. The view of the lake was very nice. We would definitely stay there again.

We were very happy with the property. Great amenities. Friends visited us and want to rent a place now as well. We would like to stay again but would request large garbage cans next to cabins, more then a bathroom sink, and the bugs were SOOOO bad at dusk, not sure what could be done about that?

Fresh tar. Lots of traffic in and out Sunday night and no protection from headlights to front camp sight. Loud music from cabin Sunday night. No mini golf. Frisbee golf and course not finished. No firewood.

This will be a great camp when the trees grow! The kids had a ball!

I have been here 2 times now and you literally have a gold mine here that is not being cared for. My hubby took a freezing cold shower before being told they forgot to put a sign on not to use. I used the other shower and it was cool. We rented a patio site and the area around the site was so washed out that we had to choose another site to level out the RV. Why no shuttle to Casino?

The park has huge potential - when it is completed

live in Waterloo Iowa, we LOVE the koa,Lost Island Waterpark, we stay there quite often,the cabins and the grounda are always clean, and this year there is table,chairs,and grills at the cabins so nice, we will be spending 4th of july there can't wait my grandkids that are twins 6yrs. old Love it out there too, great addition to Waterloo area.

We had a great time. My son caught 20 bluegills in 2 hours. For an 8 year old, that was an experience. Used the kayaks. We were surprised to learn the cabins had linens, microwave, fridge, bathroom. You can tell how much thought was put into designing those cabins. Everything had it's place.

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
Apr 21, 2014
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.
