Most people only know Quang Binh Province in central Vietnam as the home of the world's largest cave Son Doong. But if you think the province is all about caves, you will miss a beautiful, wild valley not far away.
Hung Tung Valley is around 35 kilometers to the north of the Phong Nha-Ke Bang cave system on Ho Chi Minh Road.
It has streams flowing around high limestone mountain ranges. It has lakes that look as deep as the sea.
Start your journey at Tan Hoa Commune, Minh Hoa District and ride a motorbike for around 20 minutes.
Once you see high ranges of mountains dotted with wooden houses and green corn fields, you can leave the bike. Start walking for two more hours through a primeval jungle and several small dark caves to Hung Tung.
The valley is a wonderland, strange and mesmerizing.
The first thing anyone entering the valley would do is to jump right into just any stream or lake and wash away their exhaustion in the fresh and cool water.
In order to travel through the valley, you will have to swim across streams. There will be quite a lot of climbing.
Local families are willing to host visitors with meals and overnight accommodation.
