Yas Waterworld on Yas Island is themed on the UAE's pearl-diving past, and the story runs through the whole park rather than sitting on a sign at the gate. There are more than 70 rides, slides and experiences, including Dawwama, a hydro-magnetic tornado waterslide, and one of the largest sheet waves in the world for flowriding. The range is deliberate: serious drop slides and raft rides at one end, a wave pool, a lazy river and extensive shallow play areas for small children at the other, so mixed-age groups are not stuck. There is also a pearl-diving experience, water-cinema screenings and seasonal events through the year. Allow at least four hours; a full day is easy. Bring swimwear, a towel and strong sunscreen - lockers and changing facilities are on site, and food outlets are spread across the park. During the park's Ladies Day season, Fridays (11:00-22:00) are for women only, so check the date before booking.
