Ghenh Da Dia (Rapids of Stone Plate) is located in Tuy An District's An Ninh Dong Commune in Phu Yen Province.  It comprises an unaccountable number of hexagonal rock collumns close to one another.

Here are some photos which showcase the site's pristine natural beauty and enchanting scenery.

When hot lava reached cold seawater, it turned solid and cracked, becoming the natural wonder nowadays
