Just when you think everything has been seen and discovered in the world, we are surprised to find an unexplored and completely intact location. In 1991, young farmer named Ho Khanh ventured deep into the forest of Phong Nha Ke Bang, Vietnam looking for aloe to sell. Along the way, Khanh got lost. When he sat down to rest, he heard the sounds of strong winds and water rushing through, but felt it came from underground. When he returned the next day, he was unable to retrace his steps to the uncharted area.
It would be another 18 years before Khanh and the British Cave Research Association set out to find the subterranean area. They did not realize at the time that he had discovered the largest cave in the world. Now, adventure photographer Ryan Deboodt is sharing the beauty and splendor of this hidden treasure.
