Four grandchildren INA wide age range enjoyed a full day at this water park. The add new things each year, so it's worth going back. There is enough variety to keep it interesting for youngsters to young adults, with amenities for the elders too.

Newish, clean, well maintained and managed, with a of water activities for all ages (toddlers to adults), alert and observant life guards - a very nice place for you, your family, friends and guests to go to during the summer. Food is available, but you can eat out in the parking lot with your own. Guaranteed to have a great... More

Went on a Friday. Had a good day. The lines were not long despite a good crowd....the food is medium priced for a park but you are allowed to go outside and you can picnic on the grounds so it is good for families

We went twice this year. The cost is way below anything else to do in Iowa for 6 people to go. First time spent 5 hours. The one child we brought really enjoyed it. The second time also got a cabana to relax in. That day we were there 6 hours. The adult were tired near the end, not so... More

We couldn't believe all the entertainment you can get for the price here. The six person "luxury" cabanas were worth every cent to rent but have to be reserved well in advance - locker, fridge, ceiling fan, and room for 6 to relax out of the sun. However, no handicapped access up there - everyone has to be able to... More

Bought the two day ticket and it was worth it! Had an excellent time, lots of fun! I would recommend some improvement in the bathroom area, there's only one mirror and it needs more area to accommodate personal items while changing clothes. But we had a great time! Prices are super reasonable and staff is very friendly! Would recommend this... More

The lazy river was nice and refreshing, however could use some more shade. The wave pool was dangerous! There were so many people in there. I got kicked more than once and my entire side was bruised because of it. The need to limit how many people are in each attraction for safety reasons. On the plus side, there are... More
