A spectacular view across Da Nang Bay opens up as I drive towards the summit of Hai Van Pass. The pass goes over the mountains that divide Da Nang and the coastal plain to the south from Hue and the coastal plain to the north. Looking due east, Da Nang’s downtown area is hidden by low clouds just to the left of center of this image. The city, which now has close to 1.4 million people, has expanded along the south side of the bay, with urban development now extending almost to the base of the pass.
