Limestone mountains rise above the sea with associated karst features such as domes and caves.
This area has 1,133 limestone islands of various shapes, of which 775 of the rocky islands belong to Ha Long Bay and 358 limestone islands of the Cat Ba archipelago. They are also covered with rich vegetation over sparkling emerald waters. Ha Long Bay - Cat Ba archipelago appears like a chess board made of precious stones.
Ha Long Bay - Cat Ba Archipelago is considered a geological museum, containing outstanding global value, witnessing typical changes in the Earth's historical development.
