Ganh Da Dia

Đông Hồ · CC BY-SA 2.0

A geological wonder of tens of thousands of stacked black basalt columns resembling giant piles of plates reaching into the sea.

Ganh Da Dia is a masterpiece nature painstakingly crafted from volcanic lava that cooled millions of years ago. As it solidified, the basalt cracked into remarkably regular hexagonal and pentagonal prisms, stacked together so neatly they look arranged by human hands. The whole jet-black reef spreads over fifty meters, half submerged beneath the blue waves, half basking in the sun. Waves crash against the reef in white spray, creating a scene both grand and poetic. This is one of the few stone-plate landscapes in the world, recognized as a Special National Relic and the pride of the land of golden flowers on green grass.
