Tiran Straits

 The red sands from the desert offer a visually pleasing contrast with the dark blue from the ocean. The narrow passages between the islands are extremely visible from this angle as rocks and raised ocean floors appear in vivid light blue, highlighting the multiple detours ships would need to take to navigate these waters safely.

The Straits of Tiran are the narrow passages between Egypt (left) and Saudi Arabia (right) that separates the gulf of Aqaba (top) from the Red Sea (bottom). The Strait of Tiran is named after Tiran Island (bottom, center/left) located at its entrance. The island of Sanafir (right of Tiran) is also visible on this image.
