Phong Nha Ke Bang (UNESCO)

Phong Nha-Ke Bang National Park is a natural reserve, listed as a World Heritage by UNESCO.
Situated about 200 km north of Hue, the park actually consists of two parts: the Natural Reserve of Phong Nha and the Ke Bang forest. The first part, shelters a unique network of caverns and caves, numbering 300 (of which only 20 have been explored), with an estimated total length of about 130 km. The place is extraordinary because it has, among others, the longest underground river and the largest natural cave in the world. 

The second part of the park, less known, is a virgin forest sheltering a rich flora and fauna, including 66 animal species, most of which are endangered species.

Once in the park, visitors can take a boat to reach a series of caves that will be explored on foot. Stalactites, stalagmites and other natural formations are very impressive. Outside, you can go hiking in the woods for a few hours through the dense jungle and enjoy the fascinating environment.
