Kong Sinkhole not only attracts tourists with its rich natural beauty but is also a great place to experience adventurous activities and overcome challenges to sublimate in the majesty of nature.
Introduction to Kong Quang Binh Sinkhole
Kong Sinkhole is a prominent new tourist destination in Vietnam, located in the area of Phong Nha – Ke Bang National Park , in Quang Binh province. When the Kong Sinkhole was discovered and announced, there was much controversy about whether it was the deepest sinkhole in Vietnam or not. However, current data is not enough to make an accurate assessment because when the sinkhole was discovered, the equipment and infrastructure were not yet complete. The entrance and exit of the cave have not yet been fully explored, so the depth of the hole cannot be measured.

During the expedition back in 2019, a team of explorers from Jungle Boss company (Quang Binh), the exclusive unit to exploit and develop Kong sinkhole tourism, measured the depth of the sinkhole. Results showed that the sinkhole was about 450m deep from mouth to bottom. However, because the measurement method mainly relies on manual means and has not been confirmed by cave experts, these numbers are still controversial. However, there is no denying the majesty and uniqueness of Kong Sinkhole, one of the most remarkable deep sinkholes that humans have discovered.

What is the history of Kong sinkhole discovery?
The history of the discovery of Kong’s lolot records important advances in its understanding. In 1997, a British royal cave expert participated in the annual cave exploration trip in Phong Nha – Ke Bang National Park and discovered a sinkhole hidden in the Tiger cave system. To reach this sinkhole, he had to pass through the heart of Dai A cave, known as Tiger cave.
Another notable development took place in 2017, when a cave exploration team used drones to record the landscape of the Kong sinkhole area. This image reminds many people of the monster King Kong in the movie Skull Island, a large part of which was filmed in Phong Nha.
In 2023, Jungle Boss’s cave exploration team in Quang Binh continues to research and come up with three different options to explore Kong Sinkhole. Methods include swimming through Dai A cave, using a high rope swing from the crater, and even walking from the other direction. These options create challenging and adventurous cave exploration journeys, only for those who are passionate about exploration and willing to overcome personal limits to face challenges and gain experiences. memorable for a lifetime.

From Tiger Cave, the journey continues to the Doc Luon Slope area, where overcoming the Kong sinkhole becomes more difficult with increased slope and slippery roads. You can only rely on forest trees or vines to cross Eel Slope.
After successfully overcoming Eel Slope, energy and strength may have decreased a lot. When it starts to get dark, you will reach the mouth of Dai A cave, an ideal place to set up camp to rest. A night camping in the heart of the wild mountains and forests will be an unforgettable experience.

At the top, you will see a row of limestone stalactites formed over millions of years, like giant stone spikes pointing their tips and creating small drops of falling water. At some points, you can touch the stalactites, feeling the wonder of the natural masterpiece that took millions of years to form.
