Ban Doc waterfall is situated in Dam Thuy commune, Trung Khanh district. The Quay Son river rises from China flowing into our country in Po Peo (Ngoc Khe commune) and to communes including Dinh Phong, Chi Vien. When it reaches Dam Thuy commune of Trung Khanh district, the mild river circles around Co Muong mountain bottom and flows to rice fields of Dam Thuy towards the large maize alluvial plain of Ban Gioc village. Here, the flow divides into many branches and lowers its flow to 35m creating Ban Gioc waterfall.

The sight in Ban Gioc waterfall bears a poetic, fresh, quiet beauty of water, forest and cloud area mixed with village atmosphere of mountainous ethnic minorities. Beyond the waterfall see the Vietnamese- Chinese landmark 53. This is a cultural destination for young people and ethnic people of both countries.Ban Gioc waterfall is now an attractive beauty-pot for national and international visitors.
