The Floating Playground: Features and Fun

Once you step onto the floating platform, the first thing you’ll notice is the variety of features. There are more than 20 connected elements—slides of various heights, monkey bars for swinging across, balance beams to test your steadiness, and climbing walls for those feeling a bit more daring.
The 20-foot slide is the centerpiece—a tall, thrilling descent for those who love adrenaline. It’s designed to give a sense of accomplishment when you reach the bottom, followed by a splash that cools you off instantly. The entire course is constructed to be safe yet challenging, with a focus on fun for all ages.
For the little ones, ages 4-6, there’s a Keiki Course and a shaded Ohana Splash Pad. These areas are perfect for younger children who might not yet be ready for the elevated features. Adults accompanying small children can purchase a pass at the child’s rate, making it accessible for families.
What You Can Expect on Your Day
Upon arrival at the Wai Kai site, you’ll check in with your mobile ticket, often in a small group of up to 15 people. The experience is quite flexible—once you’re on the lagoon, you’re free to explore all the features at your own pace.
Most visitors seem to start with the obstacle course, testing their agility and balance. If you’re feeling hot or need a break, the Ohana Splash Pad offers shaded fun for the kids, with water sprays and gentle splash zones. Adults can relax nearby, enjoying the scenic lagoon views or taking photos of the kids’ antics.
The lagoon itself is expansive, giving plenty of space to spread out and avoid feeling crowded. The water is typically calm, making it a safe environment for swimming, climbing, and sliding.

The floating nature of the playground means you’re constantly shifting your perspective, often with scenic views of the surrounding lagoon and nature. It’s a great way to combine physical activity with the tranquility of Hawaii’s waters.
Cost and Value

At $62.83 per person, the Wai Kai Lagoon Adventure strikes a good balance between cost and entertainment. For roughly three hours of active fun, it’s comparable to a day at a water park but with a more exclusive, scenic feel. You’re paying for a unique environment that combines water play with the natural beauty of Oahu—not just a box of plastic toys.
While the activity doesn’t include meals or transportation, the experience’s quality and scenic setting make the expense worthwhile for families and adventure lovers. The ability to move freely between features means you get a personalized day—whether you want to be daring or just relax and watch others.
