Dubai Creek is a saltwater creek located in Dubai, United Arab Emirates (UAE). It ends at Ras Al Khor Wildlife Sanctuary. Some sources say that the creek extended as far inland as Al Ain, and that the Ancient Greeks called it River Zara. Historically, the creek divided the city into two main sections – Deira and Bur Dubai. It was along the Bur Dubai creek area that members of the Bani Yas tribe first settled in the 19th century, establishing the Al Maktoum dynasty in the city. In the early 20th century, the creek, though incapable then of supporting large scale transportation, served as a minor port for dhows coming as far away as India or East Africa. Although it impeded the entry of ships due to current flow, the creek remained an important element in establishing the commercial position of Dubai, being the only port or harbour in the city.
