Wonderful place

A gret place to hang out with the family. Many types of slides and a variety of fun in the water activities. Great for all ages, too.

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

I wish it wasn't super busy every time we go. It makes it hard to enjoy yourself when you are constantly having to watch out for yourself or be trampled. The red slide left marks on my older daughters back. There's much more things to do for the older kids. The decorations give it a nice tropical feel. My favorite... More

Took the family for 18 holes of miniature golf. Haven't played in a long time. It was a decent price and we had fun. No electronics involved. They can't wait to go back again.
