The dry caves are about 400 metres deep, 40 to 45 metres high and 50 metres wide while the water-filled caves are about 150 metres deep, 20 to 25 metres high and 15 metres wide. They were all discovered north of the Truong Son Mountain Range.

Recently, there have been seven new caves containing beautiful stalactites and stalagmites found in the district of Minh Hoa.

The chairman of Minh Hoa People’s Committee, Dinh Minh Chat, says that the discovery of the new caves shows the potential for tourism in Quang Binh and will attract both scientists and investors, especially those involved in ecological tourism.
