Adventure Time

Being in Dubai is like suddenly finding yourself in a movie. It could be a James Bond movie, or a fantasy movie, or a superheroes story or some kind of a wacky cartoon about skiing in a desert. Any movie you like.

If you do not want to deal with lines and crowds at popular family destinations, keep in mind that Sunday is a working day in the UAE and Friday is a holiday.

Named “The Best Waterpark in the Middle East 2015” by TripAdvisor, Aquaventure is the largest in the Middle East and one of the most beautiful: with myth-styled attractions and lush tropical greenery, set on an apex of Palm Jumeirah island by the Atlantis hotel. The pure adrenaline moment is riding the near-28 metres, near vertical Leap of Faith slide. However some people find Poseidon's Revenge scarier. An all-day ticket costs 275 AED for adults and 225 AED for children. You can save some money by booking online.
