Jumeirah's world-famous Wild Wadi water park (admission is 200 AED) offers an incredible array of water activities. In this amazing place guests can enjoy water slides up to 128 meters long, swimming pools, an artificial river and a waterfall. The park is decorated in medieval Arabian style.
As for water-skiing and other water activities, the Persian Gulf is an ideal place for such activities. Numerous beaches, hotels and beach clubs offer wakeboarding, wakesurfing, parasailing, banana boat rides, water skiing, jet skiing - whatever you want to do!
If you plan to spend your entire vacation on water sports, stay at one of the hotels that offer them. This could be the Dar Al Masyaf at Madinat Jumeirah or the JA Palm Tree Court.
The same services are available at most beach clubs. The One & Only Royal Mirage is highly recommended for fans of active water sports, though entry costs AED250 and you'll need to reserve a spot in advance. It's the best place to combine relaxation and water activities, including sailing, fishing, windsurfing, water skiing and more.
