On May 10, Mr. Le Luu Dung, director of Junglee Boss Co., Ltd. (Phong Nha, Bo Trach, Quang Binh) said that the survey team of this unit had just discovered a mysterious lake in a side branch of the cave. Thung , belongs to the cave system in Hung Thoong.

What's special is that this lake is located about 15m higher than the main underground river branch in the cave, so this lake seems to be "hanging" on the cave wall.

Observed with the naked eye, this lake is located about a kilometer from the cave entrance and has a surface area of ​​several hundred square meters. Surrounding the lake are stalactite columns.

More time and means are needed to decode the mysteries of this strange lake - (Photo: L.DUNG).

However, the survey team is currently unable to measure the depth of the lake because there is not enough diving equipment. The group has not yet found the source of water flowing to this mysterious lake.

Because of the unique location of the lake, the survey team temporarily named the lake Lo Luong Lake.

"In the near future, we will return to Thung cave with more equipment to decode the mysteries surrounding this lake ," Mr. Dung said.

Hung Thoong is one of the most pristine places of Phong Nha - Ke Bang. Hung in Phong Nha people's language means valley.

Hung Thoong system or Thoong valley is very unique and special with many caves located deep in the strictly protected area of ​​Phong Nha - Ke Bang National Park, surrounded by a million-year-old limestone mountain system and primary forest.

The People's Committee of Quang Binh province has allowed the trial operation of the Hung Thoong discovery tour from early 2023.
