It was 1991. A Vietnamese logger named Ho Khanh was hiking through the jungle near his home in Phong Nha, in central Vietnam. Drawn by the sound of rushing water, he came to an opening in a cliff. A strong wind blew clouds out of the cave—an intimidating site, and enough to keep Ho Khanh from searching deeper—so he turned around and went about his business. That was the unceremonious discovery of Sơn Đoòng, the largest cave in the world. “It’s five miles long, 650 feet high, and 500 feet wide,” writes Ken Jennings for Traveler. “It could hold an entire city block of Manhattan, including 40-story skyscrapers.”At the time discovered Son Doong cave, Ho Khanh didn’t know about the cave value. Not long after his trip, he quit finding agarwood and went back to farming.
15 years later, the whereabouts of this cave was still in the dark. Untill 2006, when an expedition of the British Royal Association went to search for new caves in Phong Nha – Ke Bang, Khanh told his story about the cave to them. That was when the journey looking for the old cave started.
Son Doong Cave is known as the world’s largest natural cave, housing many limestone grottoes, stalactites and stalagmites. Set within Phong Nha-Ke Bang National Park (about 500km south of Hanoi), the cave is a must visit for adventurous travellers looking to explore one of Vietnam’s natural gems during their holiday.With sections reaching up to 200m tall and 150m wide and a total measured volume of 38.5 million cubic metres, Son Doong could store about 68 Boeing 777 aircraft. Even this figure may be larger because according to scientists, the most modern facilities of today has not fully explore the real length of this cave.
And somehow, it managed to remain a secret for centuries. But by 2005, the surrounding area had become something of a destination for spelunkers, and Ho Khanh realized he might have been on to something. It took three years of searching, of tracing his steps, before he was able to find the opening again, but when he did in 2009 with a British caving expedition, they became the first people to tackle Sơn Đoòng. Only a thousand or so people have done it since—including us. This is our five-day trek into the center of the earth.
