“We started yesterday morning to the park and tried to get there with all the information we gathered. We made it to Swallow Cave ( En Cave) and stayed there overnight. The next morning we were heading north-west, where relating to the National Geographic map the entrance should be somewhere after 2 km. We found the location where the river disappears into the ground and then the cave.”


Hang En (Swallow Cave) in Phong Nha National Park in Quang Binh province, Central Vietnam was voted last May 2012 by National Geographic Magazine as one of the most beautiful photos taken by NAT Geo experts. However, it’s paradoxical that few visitors know the site. That’s why we are there. From Hang En, it takes only two hours to search Hang Son Doong cave – the biggest cave passage. In a short while, we were able to spot the mouth of SwallowCave. Its beauty took by surprise. The mouth is almost 100m wide. Three huge water caves inside are separated by sloping hills which are filled with smooth sand and large rocks overlapping one another. The SwallowCave is 1.645 m long and has three mouths. One is halfway up a mountain and two others are located on another mountain which has its foot on the south-east and north-west alongside Rao Thuong Stream. All of these make the cave different from other well-known caves in the world.

According to World Wildlife Foundation report in 2000, Phong Nha-Ke Bang National Park is one of 200 biodiversity centres of the world and one of the 60 significant sanctuaries of Vietnam. It has a unique forest type in the world: green tropical forest. The park also has 15 other types of forests. The national park was created to protect one of the world’s two largest karst regions with 300 caves and grottoes.

In January 2009, the United States-based Los Angeles Times listed Phong Nha-Ke Bang National Park in its recommended world’s 29 destinations to visit in 2009. For who loves adventure, you can choose between our other 2 private tours with 1-2 nights staying inside the Park.

The best time to visit the Phong Nha National Park is from November to April (dry season) to avoid the rising water level of underground rivers inside the caves.
