Dark Cave is a branch of the Phong Nha cave system, surveyed by British explorers in 1990 and 1992. The cave has a gate 20 meters wide and 40 meters high. Like many caves in Phong Nha – Ke Bang area, Dark cave is both a water cave and a dry cave with a length of 5,258m and a height of 80m. Dark Cave is the name given by the Royal cave expedition, because the “dark light” in the cave is so thick that it makes people think it can be touched.
The cave is still pristine with thousands of colorful and characteristic stalactite pillar and a haven for many animals such as bats and swallows. In particular, the area of the cave is also a inhabited for the Hatinh langur – one of the primate species listed in the Red Book of Vietnam. Located right by the river, the humidity is high, so the stalactites at Dark Cave are covered with a large amount of moss creating a characteristic green color.
