About Phong Nha Cave


The region of Phong Nha – Ke Bang National Park gets its name from Phong Nha Cave. Not only is Phong Nha Cave one of the most beautiful caves in Phong Nha, but also one of the most historically significant and legendary caves in the whole world. Due to this cave’s sheer magnificence, travellers from all over the world find themselves astounded once inside the cave and engulfed in its magic. The stalactites and stalagmites cutting through the cave appear akin to the teeth of a giant monster and you will undoubtedly be mesmerized by the karst formations and 400 million year old limestone that surrounds you.

Discovery & Exploration

Phong Nha Cave’s earliest exploration was made in 1899. Back in the day, Phong Nha Cave served several purposes and is believed to have played a very significant role for the locals of the region during the Vietnam War.

In 1990, some British cave experts collaborated with Hanoi University of Science for an expedition inside Phong Nha Cave. The primary agenda of this expedition was to explore the depths of the cave and document it to the best of their ability.  Numerous expeditions were conducted and it led to the exploration of 10,130m of cave with an average height of 50 meters. After these successful expeditions, Phong Nha Cave became developed for tourism back in 1995.

Geological features of the cave

Phong Nha Cave has a length of 10130 meters and a 5,500 meter long underground river.

Another interesting fact about the Phong Nha cave is that it is home of a very large number of fossils that are seen embedded inside the limestone rock wall, that themselves are quite large. These fossils are believed to be that of marine creatures, like fish, seashells and possibly many others unbeknownst to researchers so far. Phong Nha Cave is about 2 million years old.

When you explore the Phong Nha Cave


As one of the best cave tours in Phong Nha, when you visit Phong Nha Cave, you will admire that the cave has some very large dry chambers and is divided in three main sections; it has been declared that all these three sections have distinct species.The three sections are the entrance zone, twilight zone and the dark zone.

The entrance zone is right at the mouth of this impressive cave and all the species of the cave that live in sunlight are found here like fish, insects and more! At the twilight zone, you’ll find that an artificial lighting system has been installed for the guests to be able to see the beauty of the cave; you may get to see crabs, shrimps, eels etc. in the water. As the name suggests, the dark zone is where you’ll be surrounded by darkness and find the presence of blind species like bats, blind spiders, blind fish and so forth. The Phong Nha Cave tour is one of the best boat tours in Phong Nha and your journey would be incomplete without it.
