On June 25, information from the Southern Quang Tri Special-Use Forest Management Board (Quang Tri province) said that the unit had established a field survey team in the Doi cave area and a large-scale subsidence pit located near the cave.
Both of these natural structures are located in mountainous forests with rugged terrain, vertical cliffs interspersed with natural forests, access conditions are extremely difficult.
Through preliminary surveys, this is an area with special geological and ecological characteristics and very high natural landscape value.
Specifically, for the Bat Cave area, the cave entrance is relatively large but hidden behind forest trees and natural rocks. Inside the cave, there is a dark, deep space, high humidity and it is the natural habitat of a large bat population densely clinging to the cliffs.
In particular, the survey team noted that the natural stalactite system here is still quite intact, with beautiful and diverse shapes with many rich colors such as gray, ivory white and light blue.
Located near the Dơi cave area is a giant subsoil pit belonging to sub-zone 638S (administrative boundaries of Hướng Phùng commune). The subsoil pit has a C-shaped structure with a wide pit mouth and vertical cliffs, many sharp cat ear rocks.
Initially, functional agencies determined that the sinkhole was formed from a natural subsidence process. The bottom of the pit is very deep, dark, and the depth cannot be accurately determined with the naked eye. This place possesses a rich vegetation ecosystem, many large trees, and vines characteristic of the limestone mountain forest.
The survey team assessed that the Bat Cave and sinkhole complex has potential for ecotourism, exploration and in-depth research on caves, geomorphology as well as biodiversity.
However, besides the rugged terrain that is prone to landslides, the survey team also discovered signs of dangerous explosives remaining at the foot of the sinkhole area. Specifically, functional forces discovered 6 bombs left over from the war (including 1 bomb that had exploded before).
Currently, functional agencies warn that this area is potentially unsafe, advising people and tourists not to approach it arbitrarily.
