Discover the thrill of Wai Kai Lagoon Adventure on Oahu, Hawaii’s only floating obstacle course. Perfect for active families and adventure seekers alike.
When it comes to fun-filled activities on Oahu, the Wai Kai Lagoon Adventure offers a unique splash of excitement. This experience, managed by The LineUp at Wai Kai, features Hawaii’s only floating obstacle course and playground, set within a sprawling 52-acre lagoon. Whether you’re traveling with kids or seeking a lively, outdoor challenge, this activity promises a blend of adventure and relaxation in a scenic Hawaiian setting.
What makes this tour stand out are its diverse features—more than 20 connected obstacles including slides, monkey bars, climbing walls, and a towering 20-foot slide. Plus, the family-friendly Ohana Splash Pad provides a safe area for younger children to splash and play, giving parents a chance to unwind while the little ones enjoy the water. And all of this comes at a competitive price of just $62.83 per person, making it a tempting option for a day of active fun.
One thing to keep in mind is that the tour is largely self-directed—you can come and go as you please during the three-hour window, which is great for flexibility but means managing your own pace. It’s best suited for those who enjoy water-based activities, family outings, or just want to experience some lively outdoor fun in a beautiful setting. If you’re looking for a relaxing day on the beach, this might not be your first choice, but if adventure and splashy fun are your thing, you’ll find plenty to enjoy here.


This activity is designed to give you a hands-on experience in a lively outdoor environment. You won’t simply watch; you’ll be jumping, climbing, sliding, and splashing your way through a network of connected features. The floating obstacle course is the heart of the experience, featuring more than 20 connected features—all floating on the calm waters of Wai Kai Lagoon.
The obstacle course includes slides, monkey bars, balance beams, climbing walls, and a tall, 20-foot slide. These features are designed to challenge different skill levels, so whether you’re a kid, teen, or adult, there’s something to test your balance and agility. The course is accessible to ages 7 and above, while children aged 4-6 are limited to the Keiki (Child) Course and the Ohana Splash Pad. Adults participating with children can purchase passes at the child rate, ensuring everyone can join in.
When you want a break from the action, the Ohana Splash Pad offers a shaded, safe space for younger kids to play freely. The splash pad’s shaded area means you can relax without worrying about sun exposure, and adults can sit nearby with a drink or snack while keeping an eye on their kids.
Throughout your visit, you’re encouraged to move freely between activities. Whether you start your day conquering obstacle features or prefer to cool off in the splash zone, the flexibility allows you to tailor your experience. The three-hour window is ample time to sample everything, especially if you’re visiting with a group or family.
Looking for more options in Oahu? Here are some other experiences worth considering.

Step 1: Arrival at Wai Kai
Located at 91-1621 Keoneula Blvd in Ewa Beach, the starting point is straightforward. The tour begins with a quick check-in, where your mobile ticket is exchanged for access to the lagoon. Since transportation isn’t included, you’ll want to plan your route to Wai Kai ahead of time—it’s a bit of a drive from Honolulu’s city center but well worth the effort for the experience.
Step 2: Dive into the Floating Obstacle Course
Once on the lagoon, you’ll be greeted with a floating landscape of adventure. Expect to challenge yourself with slides, monkey bars, and climbing features that are all interconnected across the water. The 20-foot slide provides a fun adrenaline rush, especially for those who enjoy heights and speed. The course is designed to be safe but exhilarating, making it suitable for most active individuals.
Step 3: Take Breaks at the Splash Zone
Whenever you need a breather, head to the Ohana Splash Pad. Kids love the shaded area for free splashing, while adults can relax nearby taking in the scenic lagoon views. Many reviewers appreciate this separation, noting how it allows everyone to enjoy the day without feeling overwhelmed or worried.
Step 4: Flex Your Skills or Relax
The beauty of this experience is its self-guided nature. You can spend your time conquering the obstacles, splashing around, or simply lounging with a snack. This flexibility is ideal for families with kids of different ages, as younger children can stay in the splash zone while older ones push their limits on the course.
Step 5: Wrap Up and Head Back
After roughly three hours, you’ll return to the starting point. The tour ends here, with no structured schedule—just the freedom to enjoy your time as you see fit. The maximum group size of 15 ensures a comfortable, less crowded environment, which many travelers find more enjoyable.

At about $62.83 per person, this activity offers quite a bit of value. For three hours of active entertainment, you’re paying a reasonable rate compared to other water-based attractions. Plus, the inclusion of both the obstacle course and splash pad means multiple activities in one affordable package.
This price doesn’t include meals or private transportation, so plan to bring your own snacks and arrange your transport. Still, considering the variety and quality of features, many visitors agree that the cost is justified, especially given the scenic lagoon setting.

We appreciate the diversity of activities—from high-energy obstacle courses to gentle splash zones—making it suitable for a wide range of ages and activity levels. The scenic lagoon backdrop adds a peaceful Hawaiian vibe that enhances the fun.
The self-guided approach means you can tailor your day, spending as much or as little time on each feature as you like. The separate zones for kids and adults help keep everyone comfortable, and the safety features are reassuring without dampening the adventure.
A recurring theme in reviews is how accessible and well-organized the experience appears, with many praising the friendly staff and smooth check-in process. The flexible schedule and limited group size contribute to a relaxed, enjoyable atmosphere.

While the experience offers great value, there are a few things to keep in mind. Since it’s a floating course, weather conditions can impact your day—poor weather may lead to cancellations or rescheduling, though refunds are offered if that happens.
Also, the three-hour duration means you’ll want to plan wisely to make the most of your time. If you’re in a hurry or only have a limited window, this might feel brief. Conversely, if you’re not keen on staying active for too long, this could be too intense.
Finally, transportation isn’t included, so travelers without a rental car or rideshare options will need to organize their arrival carefully.

This experience is best suited for families with children, especially those with kids aged 4 and above, thanks to the dedicated zones. It’s also ideal for adventure seekers who enjoy water-based challenges and physical activity. The scenic setting makes it enjoyable for anyone looking to combine outdoor fun with beautiful views.
If you’re traveling with a group, the flexibility and limited size create a friendly environment. However, if you prefer a more relaxed, laid-back experience without much physical activity, this might not be the perfect fit.
