Ganh Da Dia – Da Dia Reef in Phu Yen, Vietnam
Ganh Da Dia Phu Yen, Vietnam
The area is about 100 meters wide and 250 meters long, composed of an estimated 35,000 columns of basalt rocks. The rocks are dark lava columns with roughly flat surfaces of different shapes such as round, pentagon, hexagon, polygon etc. These rock columns were created from volcanic eruptions millions of years ago. When the molten basalt flows met cold water, they solidified and shaped these rare polygonal formation due to thermal contraction effects. Ghenh Da Dia looks like a gigantic beehive or a pile of dinner plates, hence they have the name – Ghenh Da Dia (The Sea Cliff of Stone Plates).
Ganh Da Dia (Gành Đá Dĩa or Ghềnh Đá Dĩa in Vietnamese, literally means The Sea Cliff of Stone Plates) is a seashore area of uniformly interlocking basalt rock columns located along the coast in An Ninh Dong Commune, Tuy An District, Phu Yen Province, Vietnam.
Ganh Da Dia is a gift from nature to us, and it is one of the five well-known sea cliff of the world including the ones from Spain, Staffa island, Scottland and South Korea.
