On the evening of 20/4, Phong Nha - Ke Bang National Park announced the discovery of Cha Ngheo cave. Located within Phong Nha - Ke Bang National Park, in Kim Dien commune (formerly Hoa Son commune), the cave measures 583 m in length and 45 m in depth.

Inside the cave, a waterfall cascades. This challenging vertical cave descends to an underground stream. The cave is still developing and remains largely unexplored, with the area holding potential for a large cave system.

Beyond Cha Ngheo cave, over the past month, the British-Vietnamese Cave Expedition Team and the Phong Nha - Ke Bang National Park Management Board surveyed and discovered 24 new caves, in addition to identifying three previously undocumented ones.

Following their discoveries, the team conducted mapping, opening avenues for scientific research and tourism development. The findings from this expedition are expected to be announced late this April.

With its seamless, less fractured limestone massifs, Quang Tri is known as the "Cave Kingdom." Over 500 caves have been discovered here, primarily concentrated in Kim Dien, Kim Phu, Phong Nha, and Thuong Trach communes. Approximately 40 caves have been developed for tourism, including Son Doong, En, and Pigmy, which rank as the first, second, and fourth largest caves globally, respectively.
