Sir Bani Yas is an island southwest of Abu Dhabi, and the largest natural island in the United Arab Emirates. In 1977, Sheikh Zayed Bin Sultan Al Nahyan established a wildlife reserve on the island, which has now become home to thousands of free-roaming animals such as ostriches, cheetahs, giraffes, sea turtles, gazelle, and the endangered Arabian oryx. Also a bird sanctuary, over one-hundred species of wild birds can be found on the island. When not spotting animals, visitors can indulge in numerous outdoor adventures like kayaking, mountain biking, dune sailing and more.
