The history of Sung Sot Cave
The history
Surprise Cave was first discovered by the French in 1901. They were amazed by its size and beauty, giving it the name “Grotte des Surprises,” which means “Cave of Surprises.” The cave has been open to tourists since the 1990s and has become one of the most popular attractions in Halong Bay.
Over millions of years, water eroded the limestone, creating the caverns and formations we see today. The cave holds signs of early human habitation, and archaeologists have found stone tools and other artifacts inside.
Folklore
Surprise Cave has a rich history that goes beyond its natural formation. Local people have created stories about the shapes they see in the rock formations. This tradition of finding familiar shapes in the rocks is common in Halong Bay caves.
As you explore Surprise Cave, your guide might point out rock formations that look like animals or objects. Some people say they can see a horse and a sword in one of the stalactites. This shape is linked to a Vietnamese folk hero named Thanh Giong. The story says Thanh Giong left these items to protect Halong Bay from evil spirits.
Why you shouldn’t miss Surprise Cave Halong Bay?
Surprise Cave is a must-visit spot in Halong Bay for many reasons. Its impressive size and unique features make it stand out among the bay’s many attractions.
The cave is split into three main chambers, each with its own character. To reach the cave, you climb 50 stone steps through a forest, then go down 10 steps to the entrance. This journey builds excitement for what’s inside.
In the first chamber, which is the smallest, you’ll find a small freshwater lake. Look up, and you’ll see what looks like a “velvet carpet” on the ceiling, made up of shiny stalactites. This room feels like a welcoming area, preparing you for the wonders ahead.
The second chamber is much bigger. Here, you’ll see huge stalactites and stalagmites in all sorts of shapes. Some people say they can see a Buddha, a bird, or even a monkey climbing on a rock column. Let your imagination run wild as you explore this space.
The last chamber is the biggest and most impressive. It’s so large that thousands of people could fit inside. This chamber has several interesting features:
- A “royal garden” with a lake and many types of plants and birds
- Small ponds that local legends say are the footprints of Giong, a mythical hero
- A stone that looks like a horse and sword, is also linked to the Giong legend
The cave’s rock formations are its main attraction. Over millions of years, water has shaped the limestone into incredible forms. Stalactites hang from the ceiling like natural chandeliers, while stalagmites rise from the floor in various shapes. The lighting in the cave highlights these formations, creating a magical atmosphere.
Visiting Surprise Cave gives you a chance to see nature’s artwork up close. It’s a unique experience that combines natural beauty, local legends, and the thrill of exploration.
