The Son Doong Cave, the largest known cave in the world

Son Doong cave is the world’s largest cave, located in Quang Binh province, Vietnam. It is found by a local man named Ho Khanh in 1991 and was recently discovered in 2009 by British cavers, led by Howard Limbert.

The name “Son Doong” cave means “mountain river cave”, It was created 2-5 million years ago by river water eroding away the limestone underneath the mountain Where the limestone was weak, the ceiling collapsed creating huge skylights.

At first, it could only be seen as a small hole of about 5 meters high which grew to more than 200 meters high after strong rains caused part of the hill above it to collapse. Eventually, they were able to vegetation away from around its entrance.

Parts of the cave are extremely wide, at some points 300 meters, enough to fit another whole side by side. Some parts are so high, you could build a 40 floors building inside.

The roof of the cavern is made up of millions of tonnes of red laterite which gives it an orange tinge from the outside. The floor is covered in huge rocks that have fallen from the ceiling or been exposed by erosive acids in the water over millions of years.

There are many smaller caves within Son Doong including areas where limestone was mined for cement for construction projects before being abandoned when it was realized how large this cave is. So far most cavers have only explored 5km’s so there is still much more to explore.
