Along the coastline of central Vietnam there are many cliff areas, but the one which is the most outstanding and beautiful could very well be the Da Dia Cliffs in Phu Yen province. It is really a masterpiece of nature.
Here's how to get to the Da Dia Cliffs from the city of Tuy Hoa: Go north on National Highway 1A about 31 kilometers. Look for the Ngan Son bridge in hamlet 6, An Ninh Dong commune, Tuy An district - stop to ask. There you will see a straight asphalt road and you take that about 12km to the Da Dia Cliffs. The Da Dia Cliffs are 50m wide and more than 2,000m long. It is listed as a national tourist site.
Geology team 703 said that the stone of the Da Dia Cliffs is basalt and that the cliffs were formed by volcanic eruption in the Van Hoa (Son Hoa) Plateau about 200 million years ago. When the molten rock spewed out into the sea, it hardened and cracked both vertically and horizontally, creating the layers of rock that we see at Da Dia Cliffs today.
The Da Dia Cliffs from a distance look like a huge beehive. It is a huge pile of hexagonal and pentagonal shaped basaltic rocks. A part of the cliffs is under the sea water while most of it is above the sea surface. The sea crashes onto the cliffs all year round and the black and yellow rocks look very smooth and shiny. In the center of the cliffs is a depression filled with still water.
Beyond the cliffs is a 3-km long sickle-shaped sandbank called Bai Bang on which there are yellow rocks lying on smooth, white sand in the shade of tropical almond trees. The seawater here is said to be very clean making it an ideal beach for both domestic and foreign tourists.
One can sit on the rocks at Da Dia Cliffs and contemplate the beauty of the sky and the sea, melt into the sun and rhythm of the sea and feel the unique beauty of these amazing cliffs.
