History and Legacy

Sung Sot Cave was first discovered by French explorers in 1901, who named it “Grotte des Surprises” (Cave of Surprises) due to its unexpectedly vast interiors and breathtaking rock formations. It consists of two main chambers — the first resembling a theater hall and the second an even larger chamber filled with towering stalactites. Over centuries, rainwater seeped through the limestone, creating these intricate formations.

Thien Cung Cave, on the other hand, carries a more mythical charm. Local legends speak of a Dragon King’s wedding taking place inside the cave, and its walls are adorned with rock formations resembling mythical creatures, flowers, and heavenly scenes. Measuring over 130 meters long, the cave’s three chambers are illuminated with strategically placed lights that highlight its natural artistry. Both caves have become iconic stops on Halong Bay cruises, blending geological history with cultural folklore, making them must-visit destinations for any traveler.
