ToggleIntroduction To Hang En Cave
The Hang En Cave, commonly referred to as the Swallow Cave, is among the most breathtaking natural wonders located at the Phong Nha – Ke Bang National Park, within the Quang Binh Province of Vietnam. This cave is renowned for its enormous size and scenic location and is regarded as the world’s third-largest cave, measuring approximately 1,645 meters, with three enormous entrances that create this remarkable landscape that is quite rare compared to the other caves in Vietnam. This cave is situated above the Rao Thuong River and is surrounded by lush rainforest.

The main reason people visit Hang En is not only because it is one of the largest caves in the world, but because it provides an experience that involves jungle trekking, crossing rivers, and the option to camp inside the cave with an emerald lake inside. Whether it’s the vast cave, the animals around the entrances, or the surreal light from the sun that filters through the cave, Hang En provides an experience like no other.
History Of Hang En Cave
Located deep in the limestone mountains of the Phong Nha-Ke Bang National Park, the Hang En Cave is not only a natural wonder but also has cultural and historical significance. The history of the cave is inextricably linked with the local people, traditions, and the process by which the world was introduced to this cave.
Origin Of The Name
With a high ceiling and a large cavern floor, Hang En has naturally served as a habitat to a large number of swifts. At dawn and dusk, Hang En is filled with breathtaking views of swifts flying out to look for food as they head to their nests. Since Hang En is an enormous cave that has served as a habitat to a large number of swifts over the years, it is not surprising that it was named Hang En, meaning Swallow Cave.
Early Human Connection And Discovery
Hang En has been known to the Arem tribe for ages, when their forefathers were nomads living within the confines of limestone caves. The Arem were seasonal dwellers, depending on their food sources, such as hunting and gathering. Deep within the Phong Nha-Ke Bang National Park lies Hang En, known as one of the world’s largest caves, with thousands of swift nests perched on top of it. The Arem, being small, nimble, and expert climbers, have developed expert techniques on how to reach the nests using wood branches, forest vines, and rope ladders secured on minute crevices on the rocks.
Swifts had long been an important part of the diet of the Arem people, and the skill of climbing up the walls of the caves and swift hunting had long been considered a passage ritual to be undertaken by all young men before marriage, as it represented their power and capacity to support a family. In recent years, with the assistance of the local government, the Arem people are now residing in fixed villages and no longer engage in this hazardous activity. Nevertheless, every year in June, the Arem people venture into the caves to harvest swifts that have fallen out of their nests.

It was rediscovered by Ho Khanh in 1990 when he traveled to look for agarwood. It would take two more years, when the British-Vietnamese Cave Exploration Team measured and surveyed the cave, before Hang En received international attention as one of the world’s most remarkable caves.
