The history of Hang En

Hang En has been known for decades by ethnic minorities living in Phong Nha - Ke Bang National Park, but it just was surveyed and published in 1994 by cave experts from the Royal Caves Associated of England. This cave is called Hang En because there are many swifts nestling and living here. This cave is formed due to the stream of Rao Thuong flowing through the Truong Son range, eroded and created faults in the Phong Nha – Ke Bang Limestone Mountain. It is one of the oldest limestone blocks in Asia with the age about 400 – 450 million years. Every year in rainy season, Rao Thuong River rose rapidly and spill into Hang En before flowing through Son Doong Cave that increases the size of Hang En. The starting point is Ba Giang slope, it takes about 2 hours to climb the mountain, follow the vicious and sometimes almost stand up path. Overcome this slope, tourists will reach Rao Thuong Valley, where you can enjoy cool beautiful blue streams. Walking along this stream about 20 minutes you will visit Ban Doong, a small village of Bru-Van Kieu people. Stopping here, you can relax and discover more interesting things about the life of friendly and hospitable people. Continuing the trip is 2 hours of slogging through streams under the hot sun at noon. This will be a real challenge to everyone in the journey. The main entrance of Hang En appears at the end of the valley, the way of sun light up the campsite at the mouth of the cave is a remarkable sight. After a hard time, tourists will receive the worth reward. Immersing into the majestic nature, you will have chance to return to the wilderness, to the world definitely different from the reality. Drew drops on the ant litter, the singing of birds with the sound of insects create the symphony orchestra in the middle of green mountains. The deeper you go in, the more chance you have to observe the different shapes of stalactites. There are two green lakes in the Hang En cave, one cold, one warm, suitable for you to dip and enjoy the beauty of nature. Especially, Hang En Cave is an ideal place for camping and having barbecue dinner.
