The largest cave in the world

Before 1991, almost no one knew about the existence of this cave. While one of the locals did not get into it. In general, local people are afraid to visit her and bypassed because they are afraid whistling sound of the underground river.

Despite the fact that the cave Son Dung was opened over 20 years ago, the first study took place only in 2009, the year.





They engaged a team of British cavers, led by Howard Limbert was.









The biggest part of the cave, located on the territory of Vietnam, is almost 200 meters wide and over 150 meters in height, with a length of about 8850 meters.







This space seems so massive that is able to accommodate an entire city street.







Inside the cave is not only an underground river and rock build-up, but a small patch of jungle.









Literally, the name of the Son Dung translated as "underground river".

















Of course, the status of "the biggest cave in the world" can be challenged on several parameters.
