Hang Én Cave in Phong Nha Caves in Quang Binh province in central Vietnam was voted last May by National Geographic Magazine as one of the most beautiful photos. However, it’s paradoxical that few visitors know the site. That’s why we are there.

 

In a short while, we were able to spot the mouth of Swallow Cave. 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 Swallow Cave 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 country. At night, we went to this stream to catch fish. This stream was abounded with numerous kinds of exotic Because of their breathtaking beauty, many people have suggested ideas to plan and develop tourism activities for Swallow Cave and other sceneries in the Phong Nha Ke – Ke Bang National Park.
