About Lost Island Waterpark
Amusement park with seasonal hours. Multiple slides & pools plus an arcade, pool hall, go-kart track, mini-golf course & concessions.
💬 What Parents Say
- Rent a cabana for the best experience with families - you get assigned staff to bring food and drinks directly to you, eliminating wait times. Multiple reviews highlight this as totally worth the investment for groups with kids.
- Bring water shoes - multiple visitors mentioned them in reviews. The park's concrete areas get hot and water shoes provide comfort throughout the day.
- Plan your day around the wave pool and lazy river as primary attractions - these are the most-mentioned features and can easily occupy most of an afternoon for the whole family.
- Food prices are significantly higher than outside vendors (expect $30+ for basic items like pizza). Consider eating before arrival or packing snacks to save money, unless you're using a cabana service.
- Download the mobile app to stay updated on special events and special offers - the park runs multiple seasonal promotions like Memorial Weekend Specials and Season Pass Appreciation Days.
