Lost Island Waterpark

Iowa's Best RV Park

The Lost Island water park is only ¼ mile from the KOA. It is open daily between June and August. Ticket prices vary depending on the time of the season and are only valid for the selected date.

Online tickets are available for purchase until midnight of the night before. Although you can get tickets at the KOA we reserved ours ahead of time. This way ensured we were able to get in during our stay. The waterpark admission includes all rides and water attractions at Lost Island. The park also offers same-day re-entry. We were able to walk to our camper for lunch and then return to the park with no hassle. 

Our Waterloo / Lost Island KOA Resort Experience 

We stayed two nights at the Waterloo / Lost Island KOA Resort on our way west towards Yellowstone National Park. This was a great way to break up the drive through the heartland of America. The first night we played disk golf and enjoyed an evening around the campfire. In addition, the kids had a great time riding their bikes around this large campground. Our second day here was spent entirely at the Lost Island Waterpark. This park was certainly more than we expected and was a nice way to break up the trip to Yellowstone. In addition, it is a great place for a family getaway for those living in the area.
