Dubai Creek is a natural saltwater creek in Dubai. It extends about 9 miles (14 km) inwards and forms a natural port that has traditionally been used for trade and transport. The creek ranges from 200 to 1,200 metres in width while the average depth is about 6.5 to 7 metres. Previously, it extended to Ras Al Khor Wildlife Sanctuary but as part of the new Business Bay Canal and Dubai Canal, it extends a further 13 km (8.1 mi) to the Persian Gulf.
