Pristine clear lake not knowing where it originates from.
The cave haves a width of 200 meters, a height of 150 meters, and at least 6.5 km in length. It surpasses Deer Cave in Gunung Mulu National Park of Malaysia (with a height of 100m, width 90m, 2km long) to rank the largest natural cave in the world.
A spectacular scene of the cave has never seen before.
The explorers were amazed by the beauty beyond imagination

The expedition members entering Swallow Cave, an underground cave was fenced by the river barrier. In the dry season the river narrowed into a small pond, but in the rainy season it can rise up to ten meters.

A cave with the width about 90m, 250m high near the cave roof, high enough to contain a 40-story building.
About the shrinking middle row, flowing a river brought the aircraft shells, accumulating in the layers on the riverbed.
Through thousands of years, calcium has surrounded the small sand particles forming the giant “pearls”.
Like a petrified waterfall, the strips near the entrance of the cave stalactites Swallow brings the green moss.
“While very large”, but almost 'invisible' until the local people found the cave by wind blowing up from the underground.
Lightning strikes somewhere where there are green grass and trees. In the forest under the collapsed roof of the cave, the explorers found the appearance of many kinds of animals such as birds, snakes, squirrels, monkeys.
The explorers passed thru a pecfect sculpture of nature, covered with moss.
From November to April, it is safe to explore cave Ken, with a small pond on a dry cave. In the rainy season, the water will engulf much the cave.
The biggest challenge for the expedition was a high stone wall about 70 m in depth blocking the 6 km in length inside Son Duong cave.
Cannot overcome this obstacle, the explorers had marked memory. They hope the back wall will be a stalactites and other natural wonders.
