For a couple of days a year the Atlantis Water Park in Dubai, gets closed down for maintenance work.
It's home to some of the largest water rides on Earth, and when they're dried out they transform to become a skateboarders dream!
Thousands of litres of water were drained so Jan Hoffmann, Alex Sorgente and Milton Martinez made the most of the surroundings and showcased their incredible skills on the monster rides.
Sorgente says, "I never had the chance to skate a waterpark before, the slides were huge and a real challenge, kinda scary but very cool. My favorite part was the roll in to the giant bank wall, I've never skated a wall so tall in my life".
