Kong Collapse in Phong Nha is arguably Vietnam’s largest sinkhole
For the past few days, several photos capturing the majestic scenery inside Kong Collapse, a gigantic sinkhole in Phong Nha – Ke Bang National Park, have taken the Internet by storm.
First discovered in 1997 by a group of explorers from England, the sinkhole has only been open lately to qualified trekkers looking for a one-of-a-kind adventure.
The Kong Collapse tour is also one the most demanding and costly expeditions in Vietnam, after only tours in Son Doong Cave nearby.
Kong Collapse – home to world’s 4th largest cave
Nested inside Phong Nha – Ke Bang National Park, Kong Collapse remains unfrequented by tourists and still retains its pristine and mysterious beauty.

Even though its precise depth in meters is yet to be confirmed, Kong Collapse is reported by many local newspapers to be the highest sinkhole in Vietnam, and probably one of the highest in the world.

A sinkhole is a large hole in the ground caused by water erosion, often containing water from the earth’s surface that flows into underground passages.
This sinkhole, formerly known as Enclosed Doline, is now fittingly renamed Kong Collapse because the entire sinkhole looks like the skull of King Kong from a bird’s eye view.

This sinkhole was discovered in 1997 by British Caving Research Association (BCRA) with the help of local people. Inside the sinkhole, a magnificent cave system with three interconnected caves was also discovered, including Tiger Cave, Over Cave, and Pygmy Cave, which is the world’s 4th largest cave that is 845M long and 94M deep.

However, the explorers couldn’t find the exit of the cave system back then, and had to retreat. A few years ago, a group of Vietnamese explorers from a tour agency called Jungle Boss returned to explore the sinkhole and discovered all the entrances and exits of the cave system.
To access the sinkhole, the explorer team had to use different types of safety equipment, following the trail through the Tiger Cave and climbing rocky cliffs.
With a lush tropical forest growing underneath, deep rivers, age-old rock formations, and a prehistoric ambiance, Kong Collapse is like a planet of its own. Adventurers who don’t flinch from going deeper into the unknown will, at a given point of the journey, be treated to spectacular sunbeams shining down the massive pit.

Even though Kong Collapse has been open to adventurers who meet the physical criteria required for the expeditions, it is one of the toughest places in Vietnam to conquer and therefore looks untouched.
