The Formation: Son Doong Cave owes its existence to the relentless forces of nature. Its origins can be traced back 2 to 5 million years ago when tectonic shifts in the Earth's crust created an extensive tunnel system beneath the limestone mountains. Over eons, the Rao Thuong River found its way into these underground chambers, meticulously carving what we now recognize as Son Doong Cave. The cave's distinctive features, including colossal stalagmites and stalactites, witness the intricate interplay between water and rock, unfolding over millennia.

Discovery: Son Doong was discovered in 1991 by Ho Khanh, a native looking for a spot to shelter from the rain while hiking through the jungle. However, his contribution to its discovery did not end there. When the British Cave Royal Association (BCRA) visited Quang Binh, he presented his discoveries and accompanied them in looking for the cave. He couldn't recall where it was, so he kept looking for it alone. He eventually led Howard and Deb Limbert of BCRA to it in 2009.

3. How big is Son Doong Cave?

Son Doong dwarfs almost everything around it! It is the world's biggest cave, with a length of about 9 kilometers and a capacity of around 38.5 million cubic meters.

The cave's spectacular dimensions continue to astound, with its largest arch reaching an astounding height of 200 meters and its widest width spreading to 150 meters. Imagine putting a 40-story building and 15,000 Olympic swimming pools within!

Son Doong's size is accentuated further compared to other noteworthy caves in the area. For example, hang En Cave, the third biggest cave in the world, is a minuscule fraction of the size of Son Doong. Son Doong is almost five times larger than Hang En and outperforms every dimension.
