  • For being in Waterloo/Cedar Falls, this a really nice water park. Very good rides, pool, lazy river and other attractions. Also have zip lines, and mini golf. Great place to go, and it's never as busy as many other water parks in other cities.
  • Great fun for everyone. And short lines. Only complaint: the stones when walking around are super hot. I did get a blister on my foot, but whether it was due to the hot stones or just walking around a lot is a mystery to me. They have a good amount of areas for little ones and adventurous little ones. There are plenty of slides and things to do. And there are some adult beverages. The Water Coaster is one of my favorite rides and it never ceases to amaze me. The Funnel and Toilet Bowl are my 2nd favorite rides. And the next best one is the racing slides in the back of the park. Nothing is better than racing family or friends.
  • Very nice waterpark, kids loved it, clean, nice variety of rides. A little expensive for the amount of stuff to do there though, and the fact that you can't bring food in drives cost up more. Also, they seem to be a bit short on shade and chairs. The propelled waterslide (tealand purple one) also nearly gave me and my wife a concussion at a few points, it simply propels you too fast and you have airtime for like 2 seconds at a time.
  • A lot of fun! A big water park that is very enjoyable!! Great for families and just young 20ish people as well.
  • Great water park, have come here for several years. The waits for rides are usually pretty short. Most of the rides are pretty standard, with the exception of the rollercoaster waterslide combo thing. I forget what it's called. They put a lot of effort into making the park look tropical, and it turned out quite nice.
