The journey to find the largest cave in the world originated from a local man named Ho Khanh. Since he was a teenager, Ho Khanh has been known as a boy who often spent weeks and weeks deep in the forest of Phong Nha – Ke Bang National Headquarter Park to trap wild animals and exploit wood with very low income.

In 1990, in a usual trip to the forest, Ho Khanh accidentally discovered a small cave gate peeking behind a cliff. While approaching, he found out much dense fog blowing out from the small cave entrance. From there, he could hear the sound of a swift-flowing stream raging from somewhere inside.

After feeling the cold gust of wind blowing out from the inside of the cave, Ho Khanh decided to return without having any check. When he got home, he forgot the exact position of the cave entrance. Additionally, he completely did not care about it as he believed that it is just like many other normal caves that he often sees on his every trip to the jungle.

At that point in time, Howard Limbert and Deb- two members of BCRA- are in Phong Nha and carrying out surveys of caves in the area. However, they were still unable to find the exact position of the Son Doong Cave entrance.

Once talking to Howard, Ho Khanh incidentally mentioned the cave entrance that he unintentionally caught sight of along with such strong winds, dense fog, and sounds coming from the cave. Howard and Deb were then very excited and urged Ho Khanh to start searching for this cave. After several unsuccessful attempts, everyone thought that this mysterious cave would never be found and it must never exist.

Everything seemed to end but it was Ho Khanh who kept silently searching for the mysterious cave for many years afterward. In 2008, on another hunting trip, Ho Khanh luckily found the location of the cave again that seemed to be forgotten. He cautiously wrote down the path in his head and tried to contact Howard. In 2009, Ho Khanh led Howard, Deb, and many other cave experts back to the cave entrance, opening up a further exploration later.
