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!

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.

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.

1. site numbers could be more visable. 2. bird poop everywhere and trash everywhere. 3. interstate traffic noise
Sep 15, 2013
Very friendly staff, many large lots and well laid out!
Sep 13, 2013
Easy to get to and the help were very nice and helpful on every thing. The camp sites we easy to get parked in.

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.

We had a family reunion here and the kids had a ball at the beach & playground equipment - the sites were long, level and wide & clean with a very nice patio,fire ring & grill - we are already planing to have our reunion here next year - good eating places across one street and a very nice golf course across the the other - I have a 41' motor home and we say this place is a 10.

It was extremely clean, and so much to do! We have stayed in the cabins as well as the campground, The showers are very clean and nice! Staff was awesome as well. Will definately stay again.

We were very pleased with our stay. We were prepared for the typical "RV Park" parking lot type facility. However we were happy to find the Waterloo KOA is much more of a campground with large grass sites, pond, beach, and swimming area. My kids, fiancee, and I can't wait to come back again! We'll be glad once they are able to get the grass more established, but being so hot and dry we understand.

Really nice. Outstanding.:-)

Fantasic stay, this will be an excellent campground once more established. For being a brand new campground it is fantastic with lots of amenities. We will be staying again in 2014 summer.

This is a new campground and there is NO SHADE. They have a swim lake but no pool. There are no lights at night so it can be confusing at night trying to find your camp site. The row numbers are confusing. Te signs are about 20 ft after the road but just before the next road. You think you should turn after the sign when, in actuality you need to turn before the sign. Map does not show trash Cab

real nice place to stay needs grass and more shade trees but they will come in time since this is the first year of business.staff very friendly and the showers were clean and kept up
Aug 28, 2013
The staff was very helpful and they will have a great park when it is finished. We look forward to staying there again as it is so close to relatives.

Restrooms, pond, trail and store are great. Not having level ground for picnic table and sitting is disastrous. All of the washouts need to be filled in, we had several falls and turned ankles.
Aug 26, 2013
Arrived late just to stay for the night. The fellow at the desk was very cordial and let us choose our own site. Baths were immaculate, although shower water and temp were not adjustable. This is a beautiful new facility with a lovely location.
Aug 25, 2013
We and our Grandkids enjoyed our stay. Our stay was August 20th and out August 23,2013. The shower house and restrooms where very clean. The beach and play area were enjoyed by the kids.
Aug 23, 2013
Need better cable service
Aug 22, 2013
Though this is a new campground, it needs some tlc. The weeds in the fire pits and around the trees, the washouts at sites, never saw a staff member in 5 days. The hill sites need leveling. Hopefully as it grows it will get better and more care.
Aug 22, 2013
The patio site was great. We had campfires every night and rode our bikes around the lake in the evening. We used the cooker to grill burgers and played disk golf on the disk golf course. Next time we will rent boats. We hooked up the cable but had no time for watching TV. We got gas and milk at the store but didn't need the donuts or pizza by the slice: maybe next time.
