6 Reviews of Waterloo / Lost Island Waterpark KOA
Something for everyone

Great RV park. Lots of room and cabin rentals for folks that don’t have an RV. The fenced dog park was fantastic for those of us with dogs. A lake with beach area and an area for fishing founded it out! Would recommend!


Just stayed one night passing through Iowa. Very pretty Campground with colorful Kabin’s and a lake for swimming or paddle boats. Level sites but not much shade.

Surprised we did not get an escort to our site as is usual at KOA’s. Did not use bathroom facilities. Laundry needed attention as it was a bit unkempt and one machine was broken and half full of dirty water.

Would stay again to try some of the other amenities.


Amazing Waterpark across the road. Very clean, well maintained campground. Gas station and nice playground on the campground

great campground

this campground was last d out very well. with nice large spaces. a lake and a water park across the street. bathrooms were very clean and even though very family oriented we did not feel overrun with kids.

Lost Island

Clean, friendly staff. Nice lake for swimming and fiahing. close to water park ( and not to close!) We would definitely stay there again

First to Review
Nice campground right next to Waterpark

Campsite and facilities were very nice and clean, though the restroom/shower house is in desperate need of ventilation. Only visited for one night, but would recommend for families. Played a bit of lake-side volleyball in the evening. Beautiful sunset!
