The site is convenient to relatives but have some flaws especially the sewer connections which are too high and sometimes uphill. This makes for drainage problems.

very clean, friendly services, cabin was great we had 8 person which accommodated us with our four grandchildren perfectly. only downfall was that we had to pay to use the paddle boats. thought they should of been included with the rental of the cabin.

Very nice new park. Great wi-fi, better than most parks we have been in.

Very clean, comfy and cool! A small cabin that utilizes space wisely. Loved it's location right next to the pond. And, my grandson's loved the bunk beds.

Great place! I stayed right after they opened and the rain had killed all but a bit of the foliage. Now its all green and a plus are the sealcoat streets and pads. I will stay again.

Everything was great with one exception. The metal edging at #11 was coming up and my daughter cut her toe on it. Great cabins! Great price!

What an amazing little treasure! We had a blast! This place has everything!! Already planning to come back!!

Could be 5 star, but 2 bc of cleanliness. Amenities, lake and cabins are AWESOME (BUT unsanitary). Guests are required to clean. Staff does some. Yet, our cabin had gross hair, LOTS of dust/dirt everywhere, floors look clean but sticky/black, sinks w/gunk, etc. - NEED a good vacuum and cleaning solutions. Beware - fleece blankets not washed daily. Guests can pickup. Staff needs to SANITIZE/CLEAN!

Campsites were clean:) Beach was nice but had quite abit of goose droppings. Bathroom/showers were not kept clean during our stay and the 30 sec stream on the showers was inconvenient. Kids enjoyed the nice play set:)

Loved it!

I think this will be a great KOA in 5 years or so when the trees mature and the lawns/landscape improves. The tent sites are brutally dangerous with "washout" ruts and overal extremely dangerous surface. Definitely the potential to break an ankle. Especially at dark.

Great place and good people, but was very disappointed in the free wifi.
Jul 22, 2014
Great location. Many sites not level. "Beach" and swimming area has been ruined by the goose droppings.
Jul 22, 2014
They're off to a great start! I'd like to see the place in 10 yrs! Our dog lovedthe wide open spaces and bark park.

Staff was wonderful, especially Ben!! Cabins were pretty good. Site could use a little bit of clean up and more trees/vegetation but I understand it takes time to get things established.

We loved our stay at the Waterloo KOA! The staff was out of this world from the time we were discussing our needs over the phone when booking our trip 6 months ago all the way through to the checkout at the end of our fun filled weekend! We plan to make this a yearly event!

Very cute cabin and nice beach.

Our stay was short only two nights. The waterpark had record attendance for the year and the longest wait in line was only fifteen minutes. We as a group

Loud neighbors till after 1AM!

I only live a short distance away but I can't wait to spend the weekend there again... hassle free weekend!!

The 8 person cabin was perfect for my family of 5 with three small children! All the kids had a room to stay and the loft worked fine for my husband and me to sleep after enjoying the fire after the kids bed time. The tables both inside and out for meals was a huge bonus! Wish all campgrounds had such a great setup! The beach and playground were amazing for us as well.

Campground was very clean and facilities were very nice. I think it would be a little more convenient if check out time could be pushed forward to 1 or 2 pm vs noon, so you don't feel so rushed in the morning
Jul 18, 2014
Clean, lots to do, close to waterpark. Will be even better once trees mature. Love the pull-thru sites...so convenient!

VERY FRIENDLY PEOPLE THERE.VERY CLEAN AND WELL KEPT. WILL GO BACK AGAIN.

Clean campground very close to fun water park. Trees are very young which provide zero shade. It was also fairly windy. It would be nice to see more kids activities that KOAs are known for. We liked the swimming beach.
Jul 16, 2014
The beach was fantastic, the restrooms very clean, the park was beautiful. We fed ducks & geese, rented kayaks,swam & had a bonfire. It was the perfect get-away. Discount tickets to Lost Island Waterpark were an added bonus!

Seemed like a very poorly designed site, utilities spaced to make it impossible to leave a trailer on rv. Lake and beach area was FILTHY w/goose dung and asst. garbage incl. glass.Bath houses/bathrooms filthy. Never saw an employee or host out visiting or helping campers. Tried to buy longer cable for tv,when not long enough was refused return.Well us like that cable will refuse to return.
Jul 15, 2014
Compared to our stay years ago this was the best ever. The grandkids had fun fishing right out the door. Will do it again real soon.

Although this campground is only a year old, it appears they have not did any upkeep since. Facilities are nice, but are new. Sites are mostly weeds, and not mowed. I am not sure they own a weed trimmer because around posts, trees, along landscaping, etc... it appears they have not been trimmed for a month. Staff was friendly. Location is good. Need to keep better appearance.

This was our 2nd stay. Clean camp sites and friendly staff in store.

Staff was great and the cabin was in good shape. Lots to do in the area and the kids were quite excited to try everything.

We stayed in a 8 person cabin. The cabin was clean and very nice. The 5 kids loved swimming and playing in the park. Found it very helpful to have laundry facilities open 24 hours. Quiet, peaceful, very helpful staff. We didn't want to come home!
