It was a great KOA. very nice sites, that were convenient. Plenty of room and beautiful views. Really excellent staff made me feel very at home.

Arrived after dark but found a very open office and courteous staffers. Nice touch having a full convenience store and gas pumps.

The site was a good size. Clean bathrooms and laundry. Would have been nice to have rec room open longer because of the rain while we stayed. Other than the weather, it was a great place to stay.

Traveling 16 days, 12 states and 8 KOAs with 20 Girls Scouts. I can't say enough about the Waterloo KOA. The staff, the sites and the facilities were great. But mother nature cut our trip short. We were prepared for the rain but with the extreme wind conditions, we lost three tents and three canopies and they are beyond repair.

Not enough shade. Tent sites were not flat enough.The beach was like a giant litter box and had to many weeds in the swiming area.

The facilities are clean, well maintained, and everything looks so new. I wish that we could have stayed longer to really enjoy all the things that the park had to offer (lake with island, disc-golf, and playground).

Nice facility, and I appreciated the full convenience store and later office hours. My ranking is based on the fact that we were tent camping. It's a facility really geared for RVs and campers, so tent camping wasn't as good for us here as at some KOAs. The tent sites were close to the highway and morning traffic was quite loud--a few yards down the slope would have been quieter.

We loved the campground and all of the amenities. The shower facilites were excellent but wish you could control the water temperature. Other downsides is the tent site is small, the fire pit was 2 feet away from the electrical box and the lack of shade. We'd come again but we'd rent a cabin or an RV.

Beautiful campground, but bathrooms are full of hairballs and not all showers work.

Very nice campground. Tenting area could be flatter. Conveniently close to waterpark. Familyhad a great time camping. We will be back.

Convenient location. Friendly staff. The traffic noise from the highway was a little loud during the night.

Nice family atmosphere.

Very helpful accommodating staff for our camping experience with young girls. They allowed us to have multiple tents near each other.

Lovely wooded area nice grass and very friendly staff. My only complaint is that in order to use the fire pit for cooking you have to purchase a grate😒

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

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.

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!!!! :)

Waterloo/Lost island is a very clean well run resort. Bathrooms were clean and staff were friendly and helpful.

The staff was friendly and extremely helpful. Our camp sites didn't quite work for the needs of our group. Thanks to Carl and Pam we were able to move our group to sites that made us more comfortable. The lake could use a good dredging, but that isn't enough to lose my 5 marshmallow rating!

Everything was nice except the water was very full of seaweed which was find of gross! Other then that very nice park.

I think this campground needs to put a closing time on the park itself. It was almost 11:30pm/12am and a large diesel pickup came right by our tent. If there was a gate and closing time that wouldn't have happened. Overall the facilities we clean and nice. We came for the waterpark next door and had a great time. The $$ off was great! Thanks Kelly

Everything was great. Campground was good. We weren't far from the bathroom. Was quiet and enjoyable. Looking forward to coming back a lot in the future.

It's very nice but experienced a few problems when we arrived didn't know where our tent sight was a lot of noise late at night and very restless stay but nice place

Unfortunately I arrived during the off-season. I can see this place being a lot of fun during the height of summer. Very handy having a petrol station as part of the site.

Great campground. It did seem strange that there was no dishwashing sink anywhere nearby (or it was not pointed out to us). Pretty inconvenient just to use the pump.

Great campground! Lots of fun stuff for families, including those with dogs (they have a dog park with obstacle course - BONUS)

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.
May 27, 2014
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.

The tent area could use a lot of improvement. The patchs of weeds made it very lumpy
Aug 28, 2013
We showed up late at night and they didn't leave any information for us even though we had pre-registered and told them we'd be arriving very late. The tent area was lumpy and uneven (not good for a tent) and the showers where cold and had no pressure.

It clean but very small tent sights to close together could hear the other people next to us and flashlights shining input tent...I liked how close to the water park it was.
Jul 28, 2013
The campground was very clean and well kept. The site was spacious and located near the necessary facilities. Thanks for a great stay!

We loved everything about our stay We ended up having a terrible storm and with 2 small childern decided it was best to leave went back up next day to pack up was shocked they refunded our money for the one night we were not staying, that sealed the deal for me for camping at KOA the only down side is the tent site we were at was hilly and very runty those sites really need to be more level

The fish like to nibble during swimming..little to no shade..other than that it was great.
Jul 15, 2013
The beach was great for two small children. Tent campsites not the best quality, washed out and not flat. Beach had little trash here and there. New campground and I am sure it will be great in the future. I hope that the management keeps it clean and well kept. Clean shower house. Water temp was too hot at first, but cooled down.
