Sapa is a small, mountain town in Lao Cai Province. It is located about 350 km northwest of Hanoi, close to the Chinese border. Here's where you'll find the Hoang Lien Son range of mountains, which includes Fan Si Pan—the country's highest peak. This quiet Vietnamese town is home to different ethnic tribal groups. There are five main ethnic groups in Sapa: the Hmong, Dao, Tay, Giay and Xa Pho. It is said that Sapa was first occupied by the first four groups, since the Vietnamese from the lowlands (better known as the Kinh) did not colonise the highest valleys.
