Aquaventure Water Park is a large water park at the Atlantis Hotel in Sanya. There are 15 large slides in the park, as well as a “water fun” playground that is ideal for families with young kids. The most challenging slide is called "The Leap of Poseidon", which drops down an almost vertical slide of 25.1 meters and passes through a shark pool tunnel. It is very exciting to feel the shark swimming around you.
