Ganh Da Dia is a natural site on Vietnam's south central coast, in the Tuy An area formerly part of Phu Yen province, about 28 km north of Tuy Hoa and 49 km south of Quy Nhon in a straight line. Its name means «plate rock reef». The site is made of prism-shaped basalt columns that look like stacks of plates. They formed millions of years ago when volcanoes erupted to the east and the cooling lava hardened and cracked into evenly shaped columns, which the waves then split crosswise into «plates». The main site covers about 2,700 square metres, with two rocky headlands running into the sea. Dark grey hexagonal columns line the edge of the blue sea, leaning and curved on the northern headland and upright, stepped like stairs, on the southern one. White waves break on the rocks, and colourful fishing boats line the nearby bay. Visitors walk across the columns among rock pools and take photos; early morning or just before sunset is best, with softer light and less heat. The rocks are slippery near the water, so watch for waves; it makes a good trip from Quy Nhon or Tuy Hoa.
