The Pinnacle Burn slide offers a 70-degree angle, providing a more compelling and exciting experience. In addition to the falls, the water park has a lazy river that circles a small pool area. 

Don’t miss the pool area on the eighth floor in Spa World Osaka! The water temperature is adjusted to correspond with seasonal temperatures. There is also a pool area for kids where even babies can play.
