When you arrive in Thung Nai in Hoa Binh’s Cao Phong district, it should come as no surprise you will be enchanted by Ha Long Bay on land and the Muong ethnic group, indigent to the region.

Legend has it that “Thung Nai”, was once a great valley covered by vast forests, and the home to countless numbers of deer.  The name, “Thung Nai” literally means “the Valley of Deer”, and hence that is how its name originated.

For decades, Thung Nai has become famous for its huge lake containing water powering the hydropower plant on Da River and the surrounding mountainous areas creating an ecosystem rich in flora and fauna.

The best time to visit Thung Nai is in the autumn and spring when the valley is filled with the romantic lake water and small islands are covered by green color of coconut trees. 

Travelling to Thung Nai, tourists can also visit Thac Bo cave - a national heritage - and discover the scenic beauty and distinctive culture of the Muong ethnic minority people.

Thac Bo is a deep cave separated by many levels. Behind the high and large entrance, visitors see multi-shaped stalactites mirrored on a limpid pond and listen to the stone musical instruments and gongs of the Muong ethnic group.

Many tourists in Thung Nai choose the Windmill guesthouse located on a small island as an ideal place for a comfortable and relaxing stay. The guesthouse area consists of a large two-storey redbrick house and a windmill offering visitors a breath-taking view of Thung Nai, and a stilt house functioning as a communal dinning place.
