First time at Lost Island. The park is clean, the lifeguards are friendly and attentive, the drink prices weren’t bad. The lines move pretty fast. The water coaster is awesome. Wave pool is fun but could be larger. Lazy River is too shallow to have...More

Every Christmas I give our three grandchildren in Waterloo IA passes to Lost Island Water Park. It’s a couple blocks from their house and THEY LOVE IT. I visited today and it’d a water park lover’s dream.

Penny - Lost Island allows life vests, and even offers them to use for FREE. They are also allowed on our rides, though riders must still meet height requirements.
