Phu Yen, a province on Vietnam’s south-central coast, is celebrated for its pristine natural beauty. Among its many gems, Ganh Da Dia—also known as Ghenh Da Dia—stands out as a true geological marvel. This striking basalt formation draws visitors from near and far, enthralling them with its unique structure and breathtaking seascapes.
A Glimpse of Ganh Da Dia – Nature’s Breathtaking Masterpiece
Nestled in Phu Hanh hamlet, An Ninh Dong commune, Tuy An district, Ganh Da Dia was officially recognized as a National Special Relic in 2020. It’s an otherworldly sight: a sprawling field of dark basalt columns, meticulously stacked and interlocked in precise geometric patterns. From afar, Ganh Da Dia looks like a colossal honeycomb, its deep, mysterious color contrasting beautifully against the shimmering blue of sea and sky.
Formed around 200 million years ago by ancient volcanic eruptions on the Van Hoa plateau in Son Hoa district, this stunning natural wonder stretches over 50 meters wide and nearly 200 meters long. Tens of thousands of basalt columns stand tightly pressed together, forming polygonal cross-sections—mostly hexagons, but also squares and circles—layered seamlessly like pieces of a vast, natural puzzle.
