Hang En (literally Swift cave), the world’s 3rd largest cave, is located in the Cave Kingdom of Vietnam, Phong Nha - Ke Bang National Park in Quang Binh province.
As considered the world’s third largest cave by volume behind Son Doong cave, also in Phong Nha – Ke Bang National Park and Deer Cave in Malaysia, Hang En has recently become one of the most renowned and impressive caves on the planet (Photo: Oxalis Adventures/Vietnam+)

While the Phong Nha-Ke Bang National Park contains the oldest karst system in Asia, between 400-450 million years old, Hang En owes its relatively young age thanks to its location on the edge of a fault zone (Photo: Oxalis Adventures/Vietnam+)
This cave is considered the second largest cave in Vietnam and third largest in the world, and it also makes up one night of the original five-day Son Doong Cave Expedition being so close to the largest cave in the world (Photo: Oxalis Adventures/Vietnam+)
