Discover Ganh da dia
Ganh da dia, located in Phu Yen Province, Vietnam, is a renowned natural wonder about 40 kilometers from Tuy Hoa City. This remarkable site was formed millions of years ago as a result of volcanic activity. When molten lava came into contact with cold seawater, the sudden temperature change caused it to cool rapidly and contract. As the lava solidified, natural cracks began to appear, shaping the landscape over time.

These fractures eventually created basalt columns with various shapes, including hexagonal, pentagonal, and circular formations. The rocks gradually stacked on top of one another, resembling enormous stone plates. This rare geological phenomenon exists in only a few locations worldwide, making ganh da dia a truly exceptional landmark in Vietnam.
Today, ganh da dia Phu Yen attracts hundreds of thousands of visitors thanks to its unique and rare natural beauty.
