Sapa lies in the north west of Vietnam and is populated by myriad hill tribe minorities. It is a trekking mecca and you can reach it by overnight train from Hanoi followed by a short car ride.
Nestled in the northern hills of Vietnam exists one of the best ethnic markets in all of Southeast Asia! On Sundays, the ethnic minorities from the surrounding villages and hills come by foot, by motorscooter, by horse, and by water buffalow for their chance to socialize, eat, drink, smoke, get a haircut, and buy produce and meat for the next week.
