Top Oahu Water Parks

Experience the floating obstacle course and playground on Wai Kai’s 52-acre lagoon with the Wai Kai Lagoon Adventure! The Wai Kai Lagoon Adventure is Hawaiʻi’s only floating playground and obstacle course. With more than 20 connected features—slides, monkey bars, balance beams, climbing walls, and a towering 20-foot slide—this attraction delivers nonstop excitement for all ages. Dash across the course, challenge your balance, or simply enjoy splashing into the lagoon. When you’re ready to cool off or take a break, head to the Ohana Splash Pad, a shaded, family-friendly water play area perfect for both children and adults. Kids can splash freely while adults relax nearby and take in the scenic lagoon surroundings. Ages 4-6 will only have access to the Keiki (Child) Course and Ohana Splash Pad. Adults only accompanying children ages 4-6 may purchase a pass at the child price as well. Ages 7+ will have access to the full course including the elevated obstacle course.
