Out in the middle of nowhere, this park was great fun. My only complaint was there is no shade and the cabanas are outrageously priced. We would have stayed much longer if we could have escaped the sun a bit. I lost my phone in the park and some kind soul turned it in so thanks!!!

Went here a few years ago, has all the fun of bigger parks. Great wave pool and lazy river. Has enough water slides and big tube coasters to satisfy everyone in your party.

Great water park overall! They have all the big slides that other water parks have. Loved the water coaster! Nice lazy river and wave pool. Only issue was the surfaces such as steps up to the slides and just the cement got extremely hot. Suggest you wear water shoes if you have sensitive feet. Lines did not seem too long... More

Have went there at least once every summer since it opened. Water slides are awesome, atmosphere could NOT be better (you would NEVER guess you were in Waterloo Iowa), it is super clean, staff is very friendly and helpful. I've been to several others, and none of them compares to it. And lucky me- 30 miles away ;) my son... More

When I went to lost island I found there was plenty to do! Although I think that they could update a few things. first of all, the park had many good slides and attractions! Although I think you could add more basic slides but it would be good if you kept it the same... Just a suggestion!! Also I found... More

We are glad you enjoyed your visit, TravelerCat! Lost Island is constantly battling those pesky inner tubes. One of the biggest challenges with them is keeping guests from pulling the plug on the tube! We will be sure to make replacing deflated tubes more of a priority. The cleanliness of the slides and stairs and slides is disappointing - our... More

The owners of this park were generous enough to spring for a waterpark usually reserved for warmer climates in the northeast part of a state that gets limited use of an outdoor experience like this aside from summer months. What a great opportunity to experience a first class collection of slides and water attractions in small town Iowa!

Great park. Lines for slides were not bad at all they went pretty fast. Staff was friendly and helpful. Overall great place to take family. Prices in the gift shop were kinda high like a big city. Lost Island worth a full day of fun

We are happy to hear you enjoyed your experience at Lost Island! Sadly, our water temperature is at the mercy of the weather. Due to the unseasonably cold temperatures lately, our pools have been chilly. Hopefully summer will arrive to give us a hand warming things up for your next visit! More

Loved it, took my 7 yr old and 3 yr old daughters there and they both had a blast. Plenty of waterslides to choose from. Wave pool, etc. Rafts are free and food was reasonably priced. A "meal" was around $6-$7 which isn't bad considering you can spend close to that at McDonald's. Plenty of lifeguards on duty as well.... More
