Photos of greatest groto in Vietnam captured by National Geographic

The cave was found by the royal British cave exploring team. Its name is Son Doong and it belongs to the Phong Nha-Ke Bang grotto system in the center of the province.

Howard Limbert, team representative, said that the cave was first discovered by a local in 1991 who forgot the location.
Limbert’s team believes this is the world’s largest cave with the height in some places reaching over 200 meters and the width over 150 meters. He said that the inside of the cave was similar to other caves in Phong Nha–Ke Bang and that it had a fast underground river, which is larger than the river in Phong Nha cave.
According to the team’s research, the area’s cave system reaches to 60 kilometers

Currently, the only way to enter the cave is climbing down by ropes from the cave Loong Son. It’s about 80m high.

A cave with the width of about 90m, cave roof in 250m height. That’s equal to a 40-floor tower in New York City (USA).
Many years ago, a cave roof collapsed has brought light into the cave and made a tropical forest in the bottom of the cave. The explorers called it the Garden of Eden.

Like a petrified waterfall, the stalactites near the entrance of the Swallow Cave have a green color of moss and algae.
“Although the cave is huge, but they are almost ‘invisible’ until you get very close to it” said Mark Jenkins, a member of the expedition. The local hunters have found the cave by winds blowing up from the ground.
In the cave, where the light can reach, the ground is covered by green grass and trees. In the forest under the collapsed roof of the cave, the explorers found the emergence of animals such as birds, snakes, squirrels, monkeys.
Through thousands of years, calcium crystals has surrounded the small grain of sand to create giant “pearls”. This “Collection of pearls” is located in the heart of the cave not far from “the Garden of Eden”.
The explorers are exceeding the perfect natural “sculpture”, covered with slippery moss.
The biggest challenge for the expedition was a 70 m-high stone wall that blocking the Son Doong cave.
Can not overcome this obstacle, the explorers marked this place and measured water levels rise during floods. They hope that behind the wall of stalactites is a large cave with many surprises awaiting.
Dry season, from November to April, is the safe time for explorers to discover Ken Cave. In the rainy season, the water will engulf most of the cave.
