Rare 350-metre waterfall discovered inside new cave in Phong Nha–Ke Bang

A survey team has discovered a new cave featuring an exceptionally rare waterfall approximately 350 metres high within the Phong Nha–Ke Bang National Park in the central province of Quang Tri, according to the park’s management board. Preliminary findings indicate that the cave descends vertically to a depth of around 350 metres. A stream flowing from the top to the bottom of the cavern forms a striking internal waterfall, an unusual natural phenomenon rarely observed in cave systems. Phong Nha–Ke Bang, often referred to as the “kingdom of caves”, is home to more than 425 discovered ones, around 50 of which have been opened to tourists. Among them is Son Doong Cave, located in the park’s core zone, known as the largest cave in the world and featuring an underground river system. VNA/Photo by courtesy
