Renowned for its breathtaking beauty, the UNESCO World Heritage Site of Halong Bay was formed around 500 million BC, as plate tectonics, marine erosion and weather have shaped the 2,000 immense limestone karsts soaring out of its jade-green waters today.

The repeated rising and falling of sea levels over the years have hollowed out some of these islets, resulting in one of the largest concentrations of caves in Vietnam and drawing millions of visitors annually to explore these magnificent natural wonders.

Situated on the island of Bo Hon is one of Mother Nature’s masterpieces: Sung Sot Cave. First discovered by French explorers in 1901 who were so astonished by its splendor and size (10,000 sqm/108,000 sqft), they nicknamed it the “Grotte des Surprises”, or “Cave of Surprises” (which also translates to Sung Sot).

Bo Hon Island, home of Sung Sot Cave

After a steep 50-step ascent to the vegetation-covered entrance, visitors are awe-inspired upon entering the first of this spectacular grotto’s two chambers. The outer chamber, known as the “waiting room,” welcomes its guests with gorgeous, colossal stalactites masquerading as chandeliers hanging from 30 meters (98 feet) above. The ebb and flow of the sea throughout Suong Sot’s history is apparent when looking up at the wave-like patterns covering its ceilings.

Stalactite “chandeliers” in the outer chamber

A narrow corridor connects to the massive inner chamber, known as the “Grand Opera House.” This magnificent grotto is truly a sight to behold, featuring a clear pond, plentiful plant-life, splendid stalagmites, stalactites and rock formations of all shapes and sizes, and the chorus of birds singing, water flowing and at times, monkeys scampering around in search of fruit and merriment.

The captivating Sung Sot Save is included as part of the our 2-night Halong Bay cruise program aboard Heritage Line Violet and Jasmine.
