Covering 6,724 square kilometres, the mountainous province of Cao Bang is now home to many Viet Nam’s ethnic minority groups, including the Tay, Nung, Dao, San Chay and H’mong.

Cao Bang has several well-known historical interest sites and natural landscapes such as the Pac Po cave, Coi Bin Church and Ban Gioc Waterfalls.
