Explore the massive third-largest cave in the world within Phong Nha-Ke Bang
Hang En Cave is a massive limestone cavern located in the heart of the Phong Nha-Ke Bang National Park, renowned for being one of the largest caves on the planet. The cavern serves as a gateway to the deeper jungle and is famous for the expansive sandy beach located inside its main chamber, which sits beside a turquoise subterranean river.
Visitors reach the cave by trekking through the jungle and crossing streams, which is a core part of the experience. Inside the main cavern, the ceiling reaches heights of over 100 meters, allowing sunlight to stream through two giant natural skylights that illuminate the campsite below. The cave is home to a large colony of swifts, which give the site its name, as Hang En translates to Swift Cave.
Access to this site is strictly regulated and requires a guided tour, as the trek involves navigating uneven terrain and river crossings. The environment inside the cave remains relatively cool throughout the year, though the humidity levels fluctuate significantly during the rainy season. It is a destination for those seeking an immersive wilderness experience rather than a casual walk-through attraction.
