In order to reach the second chamber, visitors must walk down a narrow passageway. The second chamber is known as the “Serene Castle”. This chamber is large and grand with an extremely high ceiling and has many interesting rock formations which locals identify by likening them to animals due to their shapes.
Legend of Sung Sot cave
One eye-catching rock formation is shaped like a horse with a long-sword and is linked to the legend of Thanh Giong (God Gióng). It is said that Thanh Giong protected locals by defeating aggressors, demons and evil spirits, and once his work was done he ascended to the heavens, leaving behind a stone horse and sword to continue to drive away any future aggressors.
At the exit of the grotto, there is an open area called the “Royal Garden” where there is a peaceful pond and beautiful banyan trees. Some lucky visitors get to see monkeys in search of fruit which makes for some great photo opportunities!
