Tay Bac (literally "Northwest") is one of the regions of Vietnam, located in the mountainous northwestern part of the country. It consists of four provinces: Dien Bien, Lai Chau, Son La and Hoa Binh.

The Northwest offers captivating mountain scenery; you can hike or trek into valleys around key towns. The hill tribes inhabiting the valleys here include Thai, H'mong, Zao and Muong groups. Some live in raised long houses may still dress in traditional garb. Intricate hand-embroidered clothing and silver jewelry are worn by the women.
