The Beach Waterpark is the only waterpark in Mason, Ohio. It covers 35-acre land and water area where water rides and other beach attractions are installed. It opened in 1985 and since then, it was operated by private company.

The Kahuna Beach Wavepool offers an authentic sea wave experience while visitors are enjoying the shade of palm trees and the service of cabana waiters who are ready to take food and drink orders anytime. This facility is open for all ages. There is also the Volcanic Panic which is the longest slide in the park. It features a 360-degrees spiral and 180-degree turn right before the swimmer plunge into the water waves of The Beach.

The Aztec Adventure offers the most thrilling experience in the waterpark. It is a water coaster ride which has twist and turns of approximately 500 feet above the ground. This is the only water coaster in the Midwest area. The finale of the ride comes out through the mouth of a jaguar and a plunge to the pool surrounded by cobras.

The Beach Waterpark also features Hidden Rapids. It is a man-made hillside water adventure similar with white water rafting. It is equipped with two inner-tubes that make the ride bumpy and hasty. Other facilities in the area are The Cliff (a five-storey drop to the ocean waves), Typhoon Twist (1,000 feet slide), Banzai, Twilight Zoom, Watusi, Rip Tide, Emerald Bay, and sand Volleyball Courts.

During Holiday Fest from Late November to January, the waterpark turns into an ice rink and tobaggan runs which are illuminated with lights.
