Sapa is such a colourful town thanks to the H'mong and Dzao people from the local hill tribes who head into the town's market every day to trade their produce. There's a main market every Saturday when the place is packed but there's a lower key one every other day during the week.
These people will have undergone no formal education but the arrival of foreigners has made them well aware of the value of money and many of the youngsters have picked up a basic level of English. They sell clothing and handicrafts which are popular with tourists.
Many visitors sign up for trekking expeditions out to local villages and beyond. All hotels and travel agencies in town offer half day visits to Cat Cat just 3km outside of Sapa and full day hikes to Ta Phin village which lies 10km outside town. Spectacular scenery abounds on all treks in the area. Overnight stays in minority villages such as Sin Chai are also popular options.
For stunning scenery you must get out to the Tram Ton Pass 15km from Sapa. At 1900m it is the highest in Vietnam and connects Sapa to Lai Chau. All around you are surrounded by almost vertical rice terraces and stunning mountain peaks with regular mists hovering on them. The 100m high Thac Bac waterfall on the same route is spectacular.
For the seriously fit there is a hike to the top of Fansipan, Vietnam's highest peak at 3143m. This isn't a climb to be taken lightly with potentially treacherous conditions when the weather turns bad. From Sapa to the peak is only about 20km yet experienced hikers take three or four days to complete it carrying their all their own equipment as there is no accommodation en route. Taking a local guide and even porters is a highly recommended. If you are up to such a challenge the rewards are breathtaking.
