New campground. Well laid out. Pleasant staff. Pretty open right now but once the trees grow, this will be a nice place to camp.

Expensive for a single overnight stay.

Everyone was so helpful in hosting our 24 GMC's for our spring rally. People from 7 states and everyone was so pleased. Thanks

Much better this year with the sealed roads. Now we just have to watch the trees grow.

Only I did not like was the shower head in showers. A really high pressure needle type spray was painful on your skin. No adjustment could be made to disperse it better.

Nice setup.nice of you to let us use the pavilion for morning coffee and visiting since there were so many of us wi the GMC club. Overall it was a good camping experience.thanks,

Great campground, awesome location!

Very nice new clean campground. Did not give it 5 full stars because with it being new I would expect that in the bathrooms they would not have the push button NO adjust water temp shower fixutres. That is what you get in State parks, not what I expect in KOAs, especially brand new KOA. I hate that I have to keep pushing that button every 30 seconds while trying to give kids showers.

The roads and camping sites are covered by a painfully thin layer of gravel over either tar or oil. In any case our child (over 5 but under 10) ended up with lots of the black stuff all over including their clothing. Despite the campground being less than 10% full, the public showers/toilets are still a concern

Nice campground, with plenty of things to do on site and nearby.

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.

My family and I had a wonderful time. The amenities were awesome and the staff was great very friendly very clean!! I have a 13-year-old and an eight year old and both kids want to go back. We will be returning to this KOA

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
May 27, 2014
Family liked it very much, plan on returning later this summer when water park is open

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
May 12, 2014
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
May 12, 2014
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.
May 12, 2014
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.

need more trash receptacles

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.
Apr 19, 2014
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!

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.

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.

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.
