Sung Sot cave is the largest and possibly the most frequented by visitors of all the caverns in Halong. It is also home to various rocky islets with unique shapes. The path to Sung Sot cave is through the forest canopy, allowing visitors to experience the pleasure and exhilaration of climbing the cave.


Sung Sot Cave, located in the heart of Halong Bay and the Tonkin Gulf, was named one of the top ten most beautiful caves in the world by the Czech Association of Travel Agents and Brokers.


In 1901, a French scientist visited this cave and named it "Grotte de la surprise" - the cave of surprise and wonder. This name, however, was not recognized until 40 years later. Sung Sot Cave welcomed its first visitors in 1993, just one year before UNESCO declared Halong Bay's core region as a World Natural Heritage site.

Components of the cave

Sung Sot Cave is a cave in a limestone massif. The path to the cave is through the forest greenery; you must climb 50 stone steps and then descend 10 stone steps to reach the entrance, through which you enter the cave through a small rock breach. The splendor of Sung Sot cave progressively grows whimsical and beautiful along the 800 meter-long stone walkway.

The cave is divided into three chambers. The first chamber is the smallest chamber where you can see a small freshwater lake, the ceiling covered with a layer of "velvet carpet" with gleaming stalactite chandeliers, including stone sculptures, elephants, flowers, seals, etc. This is likely a waiting room.

Connected to the first chamber by a narrow rock path, the second chamber opens an enormous space with huge stalactites and stalagmites in unique shapes. Freely use your imagination and you can see interesting rocks shaped like a buddha, a bird, a monkey climbing on the rock column, etc.

Going further inside, the last chamber is the biggest one that can accommodate thousands of people. There will be scenes related to Giong's legend. Near the entrance, there is a stone block fashioned like a horse and a long sword of Giong, and inside the cave, there are little ponds and lakes resembling Giong's footprints. The cave's highest point is a "royal garden" with a lake, many plant species, and several bird species.
