Vietnam's Kong Collapse: Exploring the Nation's Deepest Sinkhole

Vietnam unveils Kong Collapse, its deepest sinkhole, located within the stunning Phong Nha-Ke Bang National Park in Quang Binh Province. This remarkable natural wonder, approximately 50 miles from Dong Hoi City, is captivating adventurers and nature enthusiasts alike.

Unveiling the Mystery of Kong Collapse

Initially discovered in 1997 by a British caver, its secluded nature led to the moniker "the closed drain hole." Access requires navigating the challenging Dai A Cave, also known as Tiger Cave. Le Luu Dung, CEO of Jungle Boss, a leading cave exploration company, utilized drone technology to initially survey the sinkhole, its shape resembling a King Kong face, a fitting coincidence given the filming of "Kong: Skull Island" in the same province.

Dung and his team undertook a demanding six-hour expedition. Their journey involved navigating dense jungle terrain, traversing steep, unmarked slopes using only mountain goat trails as guides, and swimming through the dark depths of Tiger Cave. "The trek to Kong felt like a journey to the edge," Dung recounted. "The path was strewn with sharp rocks, and the steep inclines had us walking along the precipice. But when we finally arrived at Kong, its beauty left me speechless."

Kong Collapse boasts an impressive depth of approximately 1,476 feet (450 meters), offering three unique access routes: swimming through Dai A Cave, rappelling from the cave mouth, or embarking on a challenging jungle trek. This thrilling adventure combines jungle trekking, cave swimming, and exploration of interconnected cave systems, culminating in a dramatic 328-foot (100-meter) rappel into the sinkhole itself.

Inside, visitors encounter a breathtaking spectacle. Sunlight streams through the crater, illuminating a vast chamber adorned with ancient stalactites and stalagmites. The sheer scale and beauty are awe-inspiring. Beyond its visual appeal, Kong Collapse supports a diverse ecosystem with rare flora and fauna, including many endemic species.

Nguyen Minh Tuan, a visitor from Ca Mau, highlighted the importance of expert guidance: "The sinkhole's interior is vast and complex, requiring advanced climbing skills and caving knowledge. Safety is paramount, and teamwork is essential. The challenges only enhance the adventure." He further emphasized, "Anyone who loves exploring should visit Kong Collapse, but proper physical preparation and safety gear are crucial. Its majesty and natural beauty will leave you awestruck."

Officially recognized by the National Speleological Society (NSS) in the United States as Vietnam's deepest sinkhole, it also ranks among the world's deepest. Currently open for tourism with expert guides and trained porters, the cost ranges from $612 to $1430 per person for a three-to-five-day expedition. However, participation requires passing medical and safety skill evaluations.
