Anyway, the place is worth visiting with its almost vertical terraces with rice plantations and especially if you escape from the traditional route. As soon as you step inside the territory away from the town of Sapa, you will really see how the tribes of the area live.
I hit a good route walking through these places and reached populations where they were scared even to see me ... Although that did not happen in all places. In one of the villages I found these kids bathing naked with water buffalo in a large puddle. One of them seemed to sharpen his nails with a large machete ... so I decided, once the photo was taken, to continue my walk.
Eye anyway when taking pictures. There are some tribes in the area who believe that by shooting a snapshot of their faces, a second of their lives is lost and escapes forever from their lives. Ask before photographing them. In addition, they are not there for you to arrive and dedicate yourself to pixelate them as you wish, right?
