The site is a stretch of beach with many huge basalt columns that look like plates stacked on each other.

The main area of the Da Dia Reef scenic spot is about 2,700 m2, and the basalt stone columns there look like two capes that reach out into the sea.

The first cape sticks out in the north, with sharp, curved stone columns. The second cape is in the south and is mainly made up of stone steps and columns from low to high.

Scientists say that when many lava flows from volcanoes on the Van Hoa Plateau met the cold water of the sea, they froze and broke up.

Also, it has a strange shape that is still very perfect because of the many lava flows that continue to freeze and separate.

Other than the Da Dia rapids in Phu Yen, there are only four places in the world that were made this way:

Giant’s Causeway on the northeastern coast of Northern Ireland, Órganos Rock Rapids on the Spanish island of La Gomera, Fingal cave on Staffa Island in Scotland, and Jusangjeolli disc rapids in Korea.

Due to volcanic activity and the Van Hoa plateau, many studies show that these rocks are up to 200 million years old.
