About Wai Kai
Wai Kai is a water activity operator located in Ewa Beach, Hawaii, centered on a 52-acre crystal lagoon. The company curates lagoon-based experiences for families, beginners, groups, and athletes, combining floating attractions, guided cruises, lessons, and rentals. Offerings include Duffy Boat Cruises on eco-friendly electric boats with a captain providing local insights; beginner surf lessons designed to remove paddling and pop-up struggles with expert guidance; and a variety of modular water attractions such as AquaVenture, AquaPeakz, and the Keiki Course for young children.
Group-focused options feature the AquaPlay Party Package, an all-in-one bundle for birthdays and team outings that combines water activities with beachfront time and roughly $250 in savings. The AquaVenture & AquaPeakz Bundle pairs the largest floating obstacle course with an elevated challenge course for high-energy fun. Families can relax at the Ohana Splash Pad, a floating splash pad with shaded seating and gentle zones suited to all ages.
Additional offerings include half-day Lagoon Experience Packages (morning and afternoon) with obstacle course access and watercraft rentals that include a Paddle Pass, plus recurring adult sessions hosted by the HNL Masters Water Polo Club twice weekly for skill development. Safety features, age-appropriate circuits like the Keiki Course for ages 4–6, and guided components are integral to each experience. Wai Kai’s on-site programs emphasize accessible, family-friendly aquatic recreation in the protected lagoon environment. Reservations and scheduling accommodate varied group sizes and timeframes, with staff coordinating arrivals and equipment to streamline guest experience throughout the day to ensure safety and convenience.
