1. Overview of Sung Sot Cave Halong Bay

1.1. The Name, Legend, and History

The name “Sung Sot” means “Surprise” in Vietnamese. When visitors first approach the cave, they’re greeted by a modest, narrow entrance tucked into the limestone cliffs. But step inside, and you'll find yourself in an enormous chamber with soaring ceilings and intricate stalactites and stalagmites. The contrast between the humble exterior and the grand interior often leaves travelers amazed — hence the name.

Sung Sot Cave is not just a natural masterpiece, it's steeped in Vietnamese folklore. According to legend, the cave is tied to Thanh Giong, a mythical hero who defended the land from invaders. Locals believe the formations inside the cave resemble symbols of his battle — a horse, a sword, and even hoofprints imprinted in the rock. These mythical shapes add an air of mystique to the already awe-inspiring site.

The Surprise Cave was first discovered by the French in 1901, who named it “Grotte des Surprises” — the Cave of Surprises — for the same reason we marvel at it today. However, it wasn’t until 1993 that Sung Sot Cave was officially opened to tourists. Since then, it has become a highlight of Halong Bay excursions, drawing thousands of visitors each year.

Its massive size, surreal formations, and cultural significance make it a must-see for both nature lovers and history buffs

To gain a deeper appreciation for the region that surrounds Sung Sot Cave, make time to visit Quang Ninh Museum.
