Ocean Dome has its own flame-spitting volcano, crushed white marble "sand", and it also boasts the world's largest retractable roof, providing a permanently blue sky. Temperature, wind and humidity are closely controlled to provide an ultra-safe "sea-side" experience.
Every hour, the volcano erupts and the hi-tech wave machines start up, starting a few minutes of sanitized surfing.
Entrance cost is US $50 per person, which seems especially expensive given that there is a free, natural beach only 300 meters away.
