A joint team of Vietnamese and Japanese scientists have discovered what they believe is Southeast Asia’s longest volcanic cave system in the Central Highlands province of Dak Nong, according to Việt Nam’s General Department of Geology and Mineral Resources.
Scientists from the department and members of the Japanese Caving Association made the breakthrough discovery after seven years of research, Nguyễn Vaan Thuận, director of the department, told Tiền Phong (Pioneer) newspaper.
Thuận said the cave system is a unique vestige of a formative volcanic eruption that took place millions of years ago.
It includes 12 volcanic caves, three of which have been surveyed in detail, Thuận said.
Located mostly in Dak Nông’s Krong No District, the system stretches around 25 kilometers from a volcanic cave in Choar Village, along the Serepok River to Dray Sap Waterfall, which features dozens of caves.
Thuận said scientists have conducted detailed surveys of three caves–the largest of which measures over a kilometer in length and several thousands of meters in width.
This cave has very unique structure, he said, adding that it offers some magnificent views.
Its entrance is located deep inside a forest.
Japanese scientists said the cave system is the longest and most beautiful of its kind in Southeast Asia and will prove to be a great resource for research and tourism.
The General Department of Geology and Minerals of Việt Nam will officially announce the discovery later this week to solicit funding for further research.
Once the research is finished, the department will develop a plan to turn the cave system into a geological park, according to the department.
Lê Khắc Ghi, director of Dak Nông Province’s tourism department, said the newly-discovered caves are located in Dray Sap Forest.
Ghi said the system is fairly easy to navigate.
The caves have great potential for eco tourism and adventure travel, he said.
Việt Nam boasts many diversified cave systems dotted throughout the country–from the northwest to the central region.
The recent discovery represents the first volcanic cave system ever found in Việt Nam.
