From an early age, local man Ho Khanh used to spend weeks on end trekking and maneuvering his way through the jungles of the Phong Nha-Ke Bang National Park, searching for food and timber to earn a modest income.
When the cave is discovered?
In 1990 while out on a hunting mission, Ho Khanh stumbled across an opening in a limestone cliff and moved forward to investigate. As he approached he noticed clouds billowing out of the entrance, and could hear the sounds of a river raging from somewhere inside the cave.
When he could feel a strong wind also blowing out from the cave, he decided to move on without further inspection. By the time he had returned to his home a few days later, he had forgotten its exact location and thought no more of it.
British Cave Research Association
At the same time two members of the British Cave Research Association (BCRA), Howard and Deb Limbert, were basing themselves in Phong Nha to conduct exploratory cave expeditions in the area. While chatting with Ho Khanh one day, he mentioned to the caving experts that he had found a cave with clouds and a river inside. Howard and Deb were intrigued and urged Ho Khanh to try and rediscover the cave. After many failed attempts, they began to think this elusive cavern might remain lost in the jungle forever more.
In 2008 while out on another food gathering trip, Ho Khanh found the mysterious opening again and studiously took note of the path on how to get there. In 2009 he led Howard, Deb and a team of professionals back to the cave for the first expedition to enter what would later become known as Hang Son Doong, or ‘Mountain River Cave’
