We went during the week and park was not crowded lines were short for the slides. Park was clean and it was a good crowd. Plenty to do for all ages. Only thing I would change is there was not enough shady areas to get out of the sun.

My children and I had a wonderful time at Lost Island. The park is clean and the prices are not bad for everything the park has to offer. I refuse to subject my children to the city pools in Waterloo, Lost Island is like paradise compared to the city pool. We had so much fun and there is so much for everyone of all ages to enjoy! Next year I will be getting season passes.

This is a very nice waterpark to visit. My wife and I (late 20's) took our 3 yr. old here on July 26, 2008. There's is plenty of waterslides and fun things to do. Staff is very friendly. Not sure how reasonable the food is. We brought a couple snacks along with us. The only negative comment I have to make about this park is that the ...

I searched to find any Water Parks in Iowa and decided on trying Lost Island. So glad we chose this park it was fantastic. I have children 4 & 12 and both had the best time ever. I was suprised in all the things my little one was even able to do. This is definately somewhere you could spend all day at. My husband & I enjoyed it so much we ...

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.

I went with my husband and our two children ages 10 and 13 last summer (2006). We all loved everything about the Lost Island Waterpark! It's a little spendy but a bit less than regular amusement parks where my family doesn't all like to go on everything like we did at the Lost Island! It was GREAT!!! We had a blast and hope to go back this summer (2007)!!!

Waterloo has needed something like this for a very long time! It's great for the price!We're traveling another 15 hours back to Waterloo this coming weekend and will certainly be working this place into our schedule. The activities fulfill an interest for people of all ages. Waterloo is our home away from home. We go there a few times a year and enjoy seeing new changes there.

I like Lost Island, but there is to less of rides. Please add more rides. I know you added the Tornodo, but add more. Campare to White Water Over Georgia you guys are terrible!
