I was so pleasantly surprised with Lost Island in Waterloo. They tons of great slides and a decent wave pool to boot. I've only been to a few parks in my life, but this was the best thus far. I plan on going back next year for sure. more

Every Summer my boyfriend & I (mid 20's) go to the Lost Island Waterpark in Waterloo. We have gone for the past 4 years and have yet to have a bad experience that will not bring us back. Admission is $23/person, but we find that reasonable after going to other waterparks. We take one day out of our summer just... more

I was there on a windy day a week ago which might have affected my opinions slightly.. =( (1) Water was freezing cold.. (2) Park was smaller then what I expected for the price.. =) (1) Love the rides! more

Yesterday we went to Lost Island Waterpark for the first time since we have moved to Iowa. Being originally from the East Coast, I tend to judge things quite harshly but I am happy to say it was an awesome day. The park was priced expensive which concerned me but after being there I can understand why. Parking is free... more

First when we parked, we did not have to pay for parking. I though for sure we would have to pay something. We got there about 1:00, and parking still was easy. The slides were great. The park was really clean. I was very impressed. The staff was a lot of fun. They would splash you with water while you... more

My wife and I just visited Lost Island July 8, 2005. We have been to other large national waterparks and were skeptical about even trying Lost Island. The waterpark doesn't have the number of slides that other larger midwestern parks have, but I am so glad we gave it a chance. There is enough here to keep kids/adults of all... more
