The six-kilometer-wide Strait of Tiran (also called the Straits of Tiran) between the Egyptian mainland and Tiran Island separates the Gulf of Aqaba from the Red Sea.
This photograph taken by an astronaut on the International Space Station (ISS)
illustrates the morphology of the Strait. The relatively clear, deep-water passages of the western Strait of Tiran are visible at image left, while the more sinuous, shallow-water passage on the Saudi Arabia side can be seen at image top center. Light blue to turquoise areas around Tiran Island indicate shallow water, while the island itself is arid and largely free of vegetation. Coral reefs are also found in the strait and are a popular diving destination.
