The northern mountainous province of Cao Bang is home to picturesque natural landscapes.

Quay Son river rises from China and when it reaches ​Dam Th​uy commune of Tr​ung Kh​anh district, the mild river circles around C​o Muong Mountain bottom and flows to the rice fields of Dam Thuy towards the large alluvial plain of Ban Gioc village.

Looming in the background of rice fields are villages of Tay ethnic people with ancient stone houses on stilts, creating a nostalgic beauty.

The river forms the border between Vietnam and China. The flow divides into many branches that create Ban Gioc waterfall, a top tourist destination in Cao Bang province.

The 53m high and 300m wide waterfall is the fourth largest border waterfall in the world and was named one of the ten most spectacular waterfalls in the world by travel site Touropia.

The Government has recently approved a master plan to develop Ban Gioc waterfall tourist site, turning it into a key national tourist area. Several foreign investors are interested in exploring the waterfall’s potential.

Le Van Nho, a tourist from An Giang province, said: "I heard a lot about the waterfall. This is my first time visiting here, it’s so beautiful."

According to Pham Van Cao, Party Secretary of TrungKhanh district’s Party Committee, Trung Khanh district has carried out detailed programmes to create unique tourism products. This autumn, together with the Ban Gioc waterfall festival, the Party Committee will also create favourable conditions for businesses to explore domestic tours as well as cooperate with their Chinesepeers to develop tourism here. Along with Quay Son river, there will be tourism complexes to attract more visitors.

In 2016, the Ban Gioc tourism site welcomed more than 178,000 visitors

The site is expected to welcome approximately 750,000 visitors per year and have more than 1,000 rooms for tourists by 2020. By 2030, it is estimated to receive 1.2 million visitors and have 1,750 rooms for visitors.
