VietNamNet Bridge - After years of research, scientists from Vietnam and Japan have released initial information about a complex of volcanic caves in Krong No District in Dak Nong Province, in Vietnam’s Central Highlands, including the longest volcanic cave in Southeast Asia.

This rare cave system includes dozens of caves and craters formed by lava eruptions thousands of years ago.

The cave system has a length of about 25 km, stretching from the crater in Buon Choah Commune, Krong No District along the Sre to Serepok River to Dray Sap Waterfall with hundreds of large and small caves.

Surveys show that this is the largest volcanic cave system in Southeast Asia, including the tube-shaped C7 Cave with a length of 1,100 m, the longest in Southeast Asia; the C3 Cave of 594.4 m long, the second longest in Southeast Asia; and the 456.7 m long A1 Cave, the fifth longest in South East Asia.

The caves were formed and characterized by the volcanic eruptions of thousands of years ago, with traces of lava flows.

Together with the existing system of waterfalls, the newly discovered cave system has great potential for developing eco-tourism combined with culture and adventure tourism.

The authorities of Dak Lak Province are working with the Vietnam Museum of Geology to create a plan to turn the volcanic cave system along the Serepok River into a Global Geopark.
