The unpredictable movements of the boat provide a thrill that is not usually experienced. We will give you a lecture on how to ride correctly before the tour, so first-timers need not worry.

Small children can also experience it together!
What is Big Marble?This is a thrilling ride using centrifugal force that can accommodate up to four people on a sofa type ride.
Young children can also experience this, so the whole family can participate!

It is by far the most popular among the screamers!
What is a Giant Thriller?This is a marine sport in which you ride on your stomach with your whole body stretched out. The face is positioned just above the surface of the water, giving the rider a sense of speed!
