During an intensive survey lasting over a month, the British-Vietnamese cave exploration team, in collaboration with the Phong Nha-Ke Bang National Park Management Board, officially recorded a series of groundbreaking discoveries, with Cha Ngheo Cave being the centerpiece. This unique sinkhole cave structure features an underground waterfall, opening up new prospects for geological research and guiding the sustainable development of adventure tourism in Central Vietnam.
According to official information from the Phong Nha - Ke Bang National Park Management Board on the evening of April 20th, Cha Nghéo Cave has been identified as being located in Kim Dien commune, an area formerly belonging to Hoa Son commune. Technical parameters measured by the expert team show the impressive scale of this wonder, with a length of up to 583 meters and a depth reaching 45 meters. What makes Cha Nghéo Cave different from many ordinary caves is its characteristic vertical structure of a sinkhole. At an altitude of 751 meters above sea level, the cave entrance opens up to a journey of exploration leading directly down to a mysterious underground stream hidden deep beneath layers of millions of years old limestone.
A joint British-Vietnamese cave exploration team, in collaboration with the Phong Nha-Ke Bang National Park Management Board, has just discovered Cha Ngheo Cave, a unique 583-meter-long sinkhole cave with a majestic underground waterfall inside.
The appearance of waterfalls inside Cha Nghéo cave not only creates a magnificent natural landscape but also serves as vivid evidence of the ongoing and vigorous geological processes. Experts from the British-Vietnamese expedition believe that this system is still in its developmental stage and has not yet been fully explored.
The continuous flow of waterfalls and underground streams acts as an erosive agent, promising a large-scale, interconnected network of caves still hidden around this area. This makes Cha Nghéo Cave a "gold mine" for scientists, where hydrological patterns and stalactite formations can be observed most visually.
In just over a month, the efforts of the explorers have yielded an impressive number of discoveries: 24 new caves found and 3 others surveyed for additional information. This is a significant step in completing the geological map of Quang Binh. After completing the surveying and recording of actual images, the survey team is urgently preparing the dossier to officially announce the detailed results at the end of April. This data is not only valuable for archiving but also serves as a legal and scientific basis for management at all levels to develop plans for the conservation and rational exploitation of natural values.
With its vertical structure and developing hydrological system, Cha Nghéo Cave holds great potential for scientific research and the development of sustainable adventure tourism.
Quang Binh possesses unique advantages with its continuous limestone mountain ranges, minimally affected by major geological faults. This favorable natural characteristic has earned the province the reputation of being the heart of magnificent caves. To date, over 500 caves of various sizes have been discovered, densely distributed in communes such as Kim Dien, Kim Phu, Phong Nha, and Thuong Trach. Of these, approximately 40 caves have been developed for professional tourism, most notably Son Doong Cave, En Cave, and Pigmy Cave. These names have established Vietnam's international reputation, holding the positions of the world's first, second, and fourth largest caves, respectively.
The continuous discovery of new geological structures such as sinkholes and underground waterfalls shows that the tourism potential of this area remains enormous and shows no signs of slowing down. For investors and travel agencies, this is a positive sign to diversify exploratory tourism products, instead of focusing solely on traditional itineraries. However, along with the economic potential comes the challenge of heritage preservation. Bringing Cha Nghéo Cave and other newly discovered caves into exploitation requires a strict management strategy to ensure the pristine condition of the ecosystem within.
Cha Nghéo Cave is not just a number on a geological map, but a symbol of the vibrant life and mystery of Quang Binh's nature – a place where every step can touch the enchanting limestone pages of the earth's history.
