There were many rides to go on. Lines were not too long. Price was reasonable. Plenty of lawn chairs. Zip line was a recently added attraction. Eat food inside park or bring your own. Picnic tables outside of waterpark to eat your own food.

I returned from a 16 year hiatus from the Orlando water park mecca to be completely amazed at the Florida quality style waterpark that is Lost Island just south of Waterloo. It didn't surprise me when the Travel Channel featured it in its guide to Top Water Parks. If it sat in the middle of Orange County, Florida, with its... More

The water rides and tubing are awesome and it's a wonderful way to ward off 100 degree heat. Concessions are high as is the gate fee. Lots of teenage kids. Overall ... a good experience a few times a year.

After passing thru the entrance of Lost Island it's hard to believe one hasn't left Iowa and traveled to a tropical paradise! The venue is incredibly clean and well kept. Diligent life guards enforce safety rules and keep the people moving smoothly thru the attractions.

Good staff, great rides, and fast moving lines. My only complaint is the beer prices. Rides are fun for adults, children, and teenagers.

We live in waterloo and get passes every year. Pros: The park is very clean and the staff is well trained. I've also never had a problem leaving my bag and towels sit on my chair.

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.
