Krông Nô volcanic caves designated as national monuments in Vietnam

The Ministry of Culture, Sports and Tourism has officially designated two scenic sites within the Krông Nô volcanic cave system as national monuments. The decision, issued on October 29, 2026, covers cave A1, also known as Dung Nham or Bat cave, and cave C2, also known as C1-C2 lava cave or Crocodile cave. Both caves are located in Nam Đà commune, Lâm Đồng province.

Each cave measures over 400 meters in length with depths ranging from 3 to 10 meters. They possess unique geological structures that reflect the specific processes of lava tube formation. These sites are part of the Krông Nô volcanic cave system, which is situated within the core zone of the UNESCO Đắk Nông Global Geopark.

The Krông Nô system spans approximately 25 kilometers and was discovered by scientists in 2014. Beyond its geological significance, the area holds archaeological importance, with evidence of prehistoric human habitation dating back 6,000 to 7,000 years, including stone tools and pottery artifacts.
