En cave is situated in the core zone of Phong Nha Ke Bang National Park, Quang Binh Province in the north central region of Vietnam. It is considered as the third largest cave in the world, after Son Doong Cave in Vietnam, and Deer Cave in Malaysia.

En Cave Formation

En cave was formed about 3 million years ago since Rao Thuong Stream flowed through Truong Son Mountain Range, eroded and created the faults in Phong Nha Ke Bang Limestone Mountain. In the rainy seasons, water of Rao Thuong Stream rises quickly and spills into the cave, continues to eroding and increasing the size of the cave.

The cave is named En (Swallow) because it is home to many swallows. In 1994, En Cave was first found by the British Caving Association. The cave is 1,645m long, 120m high, 170m wide and has three gates. Two of which are entrance gates at mountain foot and the other one being exit gate at mountain slope. This is a rare feature of cave structure in Vietnam.

Entering the cave, visitors will see 3 lakes separated by small alluvial grounds and stones overlapping one another. On ceiling, cliffs of the cave also have many stalactites in unique shapes and swallow nests. The unique feature of this cave is the holes on the ceiling creating “sky wells” to shine Rao Thuong Stream.
