According to Hoang Trong Duc, chairman of Truong Son Commune, the cave is two kilometres long, eight metres high and nine metres wide. The cave is home to four branches with 100 metros of dry sections, while the remainder is flooded.
Duc added that the locality will set up a working team to assess its tourism development potential.
In mid-2023, a 1.5-kilometre cave was also found in Diu Do Village in Truong Son Commune.
