Hang Én (Swallow Cave) in Phong Nha Caves in Quang Binh province in central. However, it’s paradoxical that few visitors know the site. 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. Learn more about this package at http://www.activetravelvietnam.com/tour.php?op=detail&tourId=73 ACTIVETRAVEL ASIA
