Doi Cave located in Ly Quoc commune, Cao Bang province, has developed within a typical karst landscape, formed on limestone and siliceous limestone dating back approximately 420–385 million years. Inside the cave, a variety of speleothems can be found—such as stalactites, stalagmites, stone curtains, and calcium flows—reflecting a prolonged karstification process under humid conditions. The ceiling and walls of the cave bear traces of ancient erosion, indicating changes in the groundwater level over time. Doi Cave is one of Cao Bang’s most remarkable destinations, attracting visitors with its pristine, mysterious beauty and unique geological values that have been preserved through hundreds of millions of years of Earth's evolution.
