The Son Doong is situated below another cave in Phong Nha-Ke Bang,
though its entry passage is very difficult to traverse. The exploration
team said they had set foot on just 6.5 kilometers along the cave, as
there is a large amount of fast flowing water inside Son Doong. It takes
explorers six hours of walking through a 10 kilometer long forest path
from Truong Son Highway to reach the mouth of Son Doong cave. The
explorer added that the Quang Binh cave has beautiful stalactites and
stalagmites that are not seen anywhere else. Phong Nha-Ke Bang grotto
system belongs to the Phong Nha-Ke Bang National Park. It is a limestone
region of 2,000 square kilometers in Vietnam and borders another
limestone area in Hin Nammo in Laos. When describing the
newly-discovered cave, the team’s spokesman, Haward Limbirt, said that
it was a thing of overwhelming beauty and grandeur. He added that each
grotto has its own beauty, but he is impressed by Ca Xai. This cave is
near the Vietnam-Laos border. It is very deep and has a big lake inside.
Explorers measured the depth of this lake, but they had only 200m of
rope and the end didn’t reach the lake bed. The British team suggested
to the local authorities not to develop Son Doong Cave as a tourism site
immediately to preserve its natural beauty.
