The expedition to conquer Son Doong cave takes visitors to magnificent stalactites, underground rivers, sinkholes or even a growing forest right in the cave with unique creatures. 

From January to March, the air in Phong Nha is still chilly, helping visitors to reduce their energy when walking through the forest all day long. This is the time when the natural forests are sprouting and the trees are green. 

On sunny days, visitors will have the opportunity to admire the maximum rays of sunlight that shine deep inside the cave, illuminating a large space inside the cave. This is a great opportunity for you to take “life” photos or admire the splendid beauty of the nature. These months you will have the opportunity to take deep photos because there is less cloud inside the cave.
