Best place to escape the heat of Midwest.OK lines, clean environment and well looked after. The lazy river was really funny! Most suitable for taking your 10 ages and up children.

I believe this is the best outdoor water park in IA. Centrally located in Waterloo with a campground, golf and casino located nearby.

If you think there is a better waterpark than this in the us you are mistaken. This place is the best, short lines, on the ball staff, well looked after and a great variety of rides. Worth every penny.

Lost Island is an amazing waterpark, especially for being in Iowa. We are lucky to have it. It has become my family's favorite getaway, we are there at least 3 times a summer. The people are friendly and the entire experience is fantastic. Worth checking out, for sure.

Unfortunately we never actually made it to the park because the manager was so rude on the phone. We had an issue with our tickets and asked very politely if they could be transferred over to the 2015 season. I was then told that they were "use or lose" and if I didn't make it out then we would forfeit... More
