Campground Reviews

Jul 17, 2015
It was a very nice stay. I was hoping for a little bit bigger cabin for the five of us, but for the amount of time we were in there, it was nice.

everything was wonderful except the pullout bed, it was unfit for most anyone. Everything else was perfect!

More attention needs to be paid to the clean up of the goose poop ALL over the beach. There is NO SHADE anywhere at the beach, umbrellas would be a nice added feature.
Jul 16, 2015
lots of open space. The 'goose droppings' are a nuisance! It would be fun with kids with the amusement park nearby. The lake had lots of algae but really nice beaches.

This is a nice campground. It would be really nice if there was a pool. The lake is nice, but full of algae. We enjoyed the walking path around the lake, but you have to dodge the goose poop. A very nice place to stay. Employees are very friendly and helpful.

Very nice KOA some problems with leveling a motor home on some spots! Nice walking path and great for families!

The staff was excellent. The shower houses were clean and great. However, we felt the camp sites were very sloped and difficult to set up the picnic table and lawn chairs. The swimming beach was covered with animal feces, and the water was inudated with seaweed. We had virtually no shade even with our awning opened. Perhaps the direction of the sites should be different. We could barely connect ou

Stayed here to have family gathering and go to water park. No shade; very hot; wet slippery floors in shower house; deluxe site had utility hookups such that you could not camp next patio so it was a waste of money
Jul 14, 2015
Since this is a newer park there is very little shade if you are a tent camper like us. Also, wish all the tent sites were next to the park instead of just 3 of them. With all the RV's around you can not set up your tent and let the children play at the park and keep a watchful eye on them.

It was a very nice and quiet KOA. We had a great time. Wish the main office/gas station wasn't so far to walk from our campsite and it would be really cool if they rented golf karts.

It's a KOA!

We stayed here overnight on a recent trip to Mount Rushmore. The park is new and very nice! I would definitely recommend. Great location in the area and close to good place to eat.

Our stay was good overall! There was a lot of seaweed in the water also on the paddle boats was hard at times with all the seaweed! The bathrooms were always clean!!!! :)

Very nice staff. Clean shower house.

Great campground! Looking forward to the trees growing more so there is some shade and wind break. Would be nice if they had a miniature golf course and stated in description on KOA site. And please find ways to get rid of the over abundance of moss in the pond/lake. Overall a great place and we plan to return again next year.

This is a great campground with lots to do. My kids caught a dozen blue gills and a bass in the small lake, enjoyed swimming and playing on the beach, and played on the well maintained playground. The facilities are very clean with everything you need in the camp store if you forgot something. A great value and we will certainly be back.

Such a family friendly campground! We traveled with a large group of people and everyone had a great time. The deluxe campsite was very large the extra patio furniture was a great surprise! We will definitely return to the campground.

Extremely clean, very friendly And always ready to give a helping Hand.manager is very professional And has a great personality for the position. Very much a people person. The workers were very polite and respectful Wouldn't stay anywhere else in the area

This KOA was the nicest we have stayed in. All of the facilities were very well maintained and clean!
Jul 10, 2015
I always enjoy staying here and love the activities that are planned. This is great for the kids. The only downfall that I don't like is having to jump around the geese poop when I'm walking around the lake area.

Nice place to stay for a night. However ice machine not functioning, no options for breakfast. Showers did not allow for temp adjustment or shower head placement resulting in cold shock when first turned on and clothing getting wet.

KOA Waterloo is a wonderful camping excursion. They have everything, great service, good people plus it is a very nice camp ground. Our stay was fantastic!

Very aesthetically pleasing campground. The store was very nice; it was convenient that it was a gas station too. The beach was nice, though we didn't swim. My kids loved the playground with its Indiana Jones theme. I thought the cabins looked adorable. We had an rv site, everything great, though I had to call about the garbage bags left on our site. Overall we were very pleased.

Clean, large camp sites, Huge camp store and plenty for the kids to do at the beach! reccomend getting a site near the beach or playground if you have kids

The water in your little lake is stagnant. Also, the picture you showed on your website leads one to believe that you have a pool on site, not at a water park for additional charge.
Jul 07, 2015
We had very good stay at the Waterloo KOA, we will stay at KOA again. Thanks

Location was great. Bathrooms were really clean. The lots on hill nead their common space leveled somehow.

Very clean and quiet. Could use a pool, the lake was good for fishing and kayaking but kind of groos for swimming with all the moss and algea.
Jul 07, 2015
Beach had goose poop, water full of slimy algae, WiFi unreliable, cable actually tv antenna ota, only one play area in a very large campground. Very close to lost island water park.

Very busy weekend for Karl and crew. They did a great job. We will be scheduling another stay.
Jul 06, 2015
For the 4th of July itinerary, they didn't exactly stick to their schedule of activities. The bottle toss started 30 mins. late, the sack races took place shortly after the bottle toss, but we didn't know that. It was to start at 7:15 - 7:45 p.m., which it didn't. The hayride started an hour late (to start at 5 p.m. and didn't start till 6 or after). Movie was on time and so was mini circus.

The KOA Lost Island in Waterloo, Iowa was great! The beach and swimming pond were clean. New shower and bathroom facilities. Large lots, although grassy areas were very bumpy from water run-off, were level for the camper. We will definitely be staying here again!
Jul 06, 2015
Very nice campground! Lots to do, wish we could have stayed longer!!!
Jul 06, 2015
The weekend was great. KOA has a very nice campgrounds, we will go back again. The only problem was that the lawn washed out on several camping spots and my daughter and another camping friend both twisted there ankle and put a damper on there weekend. I feel that the washout will remain there until they put sod down to stop the rain from washing them 4 to 6 inch holes. Like I say we will go back.

Very nice campground. Lots to do and very clean!
